Two men, Marcel (Daniel Bonjour) and Sebastien (Gilles Marini), struggle through the rain. The men wear what appear to be French military uniforms and say they are running from British soldiers. Sebastien collapses face down in the mud, Marcel picks him up and helps him to move on.

(Marcel and Sebastien are apparently in Canada in 1760 during the Seven Years War (1754-1763). This would place the Beast of Gevaudan storyline in 1764 after they've returned to France.)

At some point, Sebastien writes a letter to his sister Marie-Jeanne. He explains that, even with the help of their "Indian" allies, they are losing the war. Montreal has reportedly fallen to the British and both Marcel and Sebastien are injured.

The men take shelter in a small shack. A British search party, with dogs, can be heard in the storm outside. The woman inside says they should look elsewhere for shelter because there is a creature of the night at large in the land. She describes it as a "Shapeshifter, a demon." When pressed by Sebastien she says it's a "demon wolf."

Outside, the British advance as the rain pours and the lightning flashes. They are taken out one by one by an unseen, growling attacker. One Brit makes it inside but the growls follow and pulls him back out. Sebastien's letter is seen lying on the floor of the shack.

Gerard explains that the letter made its way into the hands of Marie-Jeanne (Crystal Reed). He describes her as a "skilled hunter" and says she would later face the beast with nothing more than a "steel-tipped pike."

Marie-Jeanne stalks an unseen animal through the snow-covered woods above Gévaudan, France.

Gerard says that she would be known to history as the Maid of Gevaudan.

Lydia and Parrish have been listening to Gerard tell the story. Parrish says maybe somebody should resurrect Marie-Jeanne to take on the beast. He heads for the exit. asks him to stay but he explains that he is not just a harbinger of death, he's the cause of it. Lydia follows after but Gerard says they should let him go. Chris says Jordan isn't their only hope of stopping the Beast. Gerard believes Lydia may be able to stop it.

Liz, who is holding the gravely injured Liam after somehow running in to the Beast, has just burst through the front doors to the school amid the chaotic flood of students fleeing for their lives. She pauses for a brief moment when she hears the Beast roaring behind them until Liz looks at Liam in alarm.

"Come on! Come on" She says to him while trying to pull him with her. She rushes into the nearest classroom and lays Liam flat on his back on top of the desk.

"Liam..." Liz whispers.

"I'm okay! I'm fine" Liam states after groaning in pain.

Liz begins pulling away Liam's jersey, which has been ripped to bloody shreds by the Beast's claws, and gasps in horror when she realizes just how serious the wounds to his torso are. Liz puts her hand over her mouth to muffle her alarm. Liam sees the concern on her face and tries to sit up to see for himself, only to fall backwards weakly.

"What? Is it bad?" Liam asks.

"No!" She tries to reasure him. "Okay, you can do this" She whispers to herself and places her hands on the wounds. "Vulnus sanandum, cura. Sana citius. Vulnus sanandum, cura. Sana citius" She mumbles the spell a few times with her eyes closed and then slowly opens them. She sighs in relief when she says the wounds have healed.

"That was... thank you" Liam says, not sure what to really say.

"To be honest I didn't think it would work" Liz admits and Liam chuckles.

Gerard says Lydia and Marie-Jeanne are similar in that they are skeptical of their own abilities and were both once skeptical of the supernatural.

In an Inn in Gevaudan, a man is about to tack up a sign that details the search for "LA BETE." Marie-Jeanne fires a crossbow bolt into the sign, tacking it to the wall. He thanks her. Marie-Jeanne reads the letter from her brother and the barman says she should not give up hope.

At another table men discuss the attack on an 11-year-old girl, she was torn limb from limb. They discuss the varying descriptions of the beast. Some say it is party hyena, part wolf, that it has red fur, black fur, cloven hooves or a stripe down its back. The barman joins the conversation saying they know it kills at night and targets the head and neck. They say "Where the beast finds a lamb, there it seeks another." They say it never eats its victims, killing for sport which no animal does. There is word that the king is planning to send professional hunters to Gevaudan to kill the beast. Until they arrive the suggestion is to use volunteers for a hunting party.

Sebastien arrives in the Inn and says the best hunter in Gevaudan is Marie-Jeanne. Brother and sister embrace. Marcel tells the barkeep he will still have a job.

The old man looking for volunteers to hunt the beast agrees with Sebastien and asks Marie-Jeanne to lead the search for the beast. The other patrons in the bar begin to chant her name. Marie-Jeanne plays it off as a joke, saying she hunts animals not rumors. The laughter dies down when a man (Henri) carrying the body of a young boy (Emile) enters the inn. Emile is the barkeep's son. His last words were "La Bete." Marie-Jeanne says she does not know what creature is responsible for the death but she will lead the hunting party at dawn.

In Beacon Hills, the beast throws Scott into a wall at the school. He's quickly back on his feet and turns to face it but the beast scurries off to another part of the school. Scott gives chase.

~~~

Lydia wonders why Sebastien didn't warn Marie-Jeanne about the beast. Gerard says they'd talked about everything he'd seen during the war but Marie-Jeanne was a skeptic.

Early morning the hunting party is gathering their weapons at the inn. Marie-Jeanne is chiding her brother for being superstitious. He assures her he saw it with his own eyes. Marie-Jeanne says she's been through every inch of the woods and hunted every creature under the sun. Marcel points out that she's not hunted under the moon. Sebastien says she will need more than ordinary steel to stop the beast.

As the hunters set out, Marie-Jeanne sees Marcel locking the cellar door.

Gerard says they hunted from dawn to dusk searching for the beast as it slept. It was just after midnight when the first torch went out. The hunting party is attacked one after the other. Marie-Jeanne looks into the darkness trying to get a bead on the beast. She manages to hit the beast with an arrow. She gets scratched and drops her crossbow. She pulls out her knife. She spies the beast's glowing white eyes and prepares for its attack.

Henri (Lachlan Buchanan) comes running from the darkness, tells Marie-Jeanne to get down and casts a circle of Mountain Ash dust. The beast slams into the barrier but can't get through. The beast runs away. Henri explains that the beast is a werewolf.

~~~

Malia is making her way through the screaming throng of students running through the hallways at the high school. She grabs a guy and slams him against the wall, demanding to know where Stiles is. He doesn't know. She takes out her phone and calls Braeden and tells her to bring all her shotguns to the school.

A girl falls in the hallway and backwards crabwalks away from the approaching beast. Scott grabs her and throws her roughly into a classroom and barricades the door with his body. The beast is right outside the door. Scott yells at the girl to go out the window. She does, just before the beast rips the door and Scott out of the room.

~~~

Lydia senses something and almost collapses. Chris catches her but she wants to leave because something is wrong. Gerard says she should hear the rest of the story. Lydia says everything she's read says the beast was killed by Jean Chastel. Gerard says the internet (and apparently Allison in season 1) got it wrong. Chris says Gerard knows the story better than anyone.

Henri brought Marie-Jeanne to his home which was protected by a circle of Mountain Ash trees. He has more Mountain Ash and Misstletoe in small bottles on his table. He says he's been gathering the knowledge and supplies to survive a werewolf. He offers to teach Marie-Jeanne but she says she doesn't want to "survive" one. She wants to kill one.

~~~

Scott runs to the Library. Sydney and more than a dozen other students are hiding behind shelves and book carts. Scott sees Selene and Brett trying to get everyone quietly upstairs. The Beast growls.

"Everyone. Now" Selene says and everyone apparently knows what she means. They all hurry upstairs and make it to new hiding places just before the beast comes in. Scott's eyes flash red just as Selene's and Brett's flash yellow as they growl back.

~~~

Gerard explains that Marie-Jeanne knew she couldn't just arm a new hunting party with "mistletoe and rowan berries." She needed an advantage.

Marie-Jeanne pours wine for everyone in the inn and says she expects everyone to drink in honor of the dead. The drink appears to have a bitter taste. Marcel breaks his glass cutting his hand. Marie-Jeanne takes him outside to the well to wash the blood away. She asks for a cloth to wrap his wound but instead he gives her the key to the cellar saying she'll find what she is looking for in there.

She takes the key, opens the door, descends and finds a pile of dead bodies. She returns to Marcel with crossbow drawn. He begs her to kill him. He reaches for the bow and the arrow flies up and away as Marie-Jeanne jerks back. Seeing his blood on the snow, she realizes that Marcel is not the killer, merely covering for him.

Inside the inn, Sebastien begins to cough and gasp. His eyes glow white. Gerard says the maid confronted her brother the moment she walked back in. She says he's killed children. He says he kills whatever there is that crosses his path. He says it's what he is, what he has become. He apparently drank rain water from the paw print of the wolf while running from the British in Canada. He says, according to the old story, when you drink from the print you become the demon wolf.

While hiding from the British, Sebastien transformed and killed the woman in the shack and all the soldiers outside.

At the inn, Sebastien dares his sister to tell the others that he is the beast. He promises to tear them apart in a matter of moments. Marie-Jeanne is in tears as Sebastien kisses her on the head, promises that she'll never catch him and walks away.

Gerard explains that Marie-Jeanne and Henri worked together to figure out how to kill the beast. Henri says they need a weapon that will use the beast's weight against itself. They forge a steel spear tip in the shape of a fleur-de-lis. Marie-Jeanne's blood runs down the blade as she places it on the staff.

~~~

Scott, Selene and Brett are getting beaten badly by the beast in the Library but keep coming back for more. As they turn to face the creature once more, Liam leaps from behind and drives his fists into the beast's head. Braeden follows up with several shotgun blasts and Malia runs toward the fray. Apparently having had enough of the fight, the beast leaps through the library's giant window and into the night. Selene almos collapses but Brett and Scott catch her.

"I'm fine" Selene whispers weakly.

"You didn't seriously think you'd have a chance against that thing did you?" Braeden asks.

"No," Selene says and stumbles forwards. "But we got it's sent" She explains and starts running after the sent.

~~~

According to Gerard, Marie-Jeanne hunted Sebastian for three years, finally cornering him in 1767. Marie-Jeanne runs through the snow apparently fleeing from her brother who is in human form with an arrow sticking out of his arm. As he follows, black, smoke-like shadows rise from the snow and coalesce around him to form the beast. As the beast is now quite close, Marie-Jeanne slides along the ground and picks up the spear that was hidden in the snow. She quickly turns to face Sebastien. Momentum carries the beast onto the spear which protrudes out his back.

Sebastien becomes human again and calls the spear sticking through his body a "minor injury." He says he will recover and kill everyone they know and history will remember his name. Marie-Jeanne explains that no one will remember. He realizes she's talking about Damnatio Memoriae and becomes angry that she plans to take his name. He suddenly starts bleeding black goo and realizes that the spear has substantially damaged him. Marie-Jeanne explains that the spear is not ordinary steel, Wolfsbane and Mountain Ash, forged with her blood under the light of a full moon.

Marie-Jeanne kisses his forehead and declares that history might remember Sebastien, but only as a beast. Sebastien falls in the snow and dies. Marie-Jeanne takes her spear and walks away.

Chris explains that Sebastien was erased from history, every signature, every possession. Gerard says they burned it all. He says the name Sebastien Valet has been forgotten for more than 150 years. Chris says when the beast remembers who it is the teenager inside is forgotten, gone forever.

Lydia points out that Marie-Jeanne did not defeat the beast alone. She had the help of Henri, the magistrate, the whole town and even Marcel. She says they need Parrish.

Jordan Parrish leaves his gun and badge on the Sheriff's desk and walks out.

Lydia wants to find Parrish but Chris says he's dangerous because he is a shapeshifter who's only learning how to use his power. Lydia thinks she's in the same position but Chris says they're not the same. He says Lydia can access the supernatural, it works through her, but she isn't controlled by it.

Lydia confronts Gerard about why he is suddenly on their side. He slides her a lighter with a fleur-de-lis etched in the side and explains that Marie-Jeanne married Henri Argent. She was the first of the Argents. Lydia exits saying she is not an Argent and she's not Allison.

Selene, who is still limping and covered in blood, seems to be on a mission as she rushes through the halls and out the side door of the school with Scott close behind and not in a much better state. Meanwhile, Liam and Brett, who are also covered in blood but seem to be more or less healed from their injuries, follow after them and try to stop them with matching worried expressions.

"Scott, Selene, wait!" Liam yells.

"Guys! Calm down" Brett adds.

The two Alpha's are panting for breath but ignore them, pushing the side door open and heading toward the parking lot as they follow the Beast's scent. Liam and Brett follow behind them and continue to try and stop them. "You're hurt! You gotta slow down!" Brett points out and shares a concerned look with Liam.

When Scott and Selene continue on without them, Liam and Brett sigh in exasperation before sprinting after them. The four quickly walk through the rows of cars in the parking lot, where Selene eventually stops behind a familiar-looking shiny black car, which apparently is where the Beast's scent led her. Scott puts his hands on the trunk door and musters up all the remaining strength he has to open it despite it being locked. Once its open, Liam, Brett, Selene and Scott gape in shock when they see that the trunk has nothing but a pair of black Converse high-top sneakers sitting nearly inside. Everyone shares a worried look before Scott picks up the shoes, which have a liberal amount of blood smeared across the soles. Scott looks at Liam anxiously, and their concern turns to horror when Scott shuts the trunk door and finds Mason standing beside the car, looking at them in confusion.

"Scott? What are you doing to my car?" Mason asks.

"...It's you" Scott says, sounds tired and disbelieving. Mason doesn't seem to know what he's talking about, and only becomes more scared and concern as he turns toward Liam, who is stunned speechless."What? Liam, what's he talking about?" Liam's look of devastation only makes Mason more terrified. Selene suddenly frowns.

"Corey! Don't!" She yells and runs toward Mason but she's too late. Corey becomes visible, grabs Mason and becomes invisible again. "Corey!" She yells and suddeny her legs give in. brett is just in time to catch her.
