She woke up in her wolf form besides Remus, he looked better than most full moons. He woke up slowly, and stared at the black wolf that cuddled him. He smiled, she stood up and fetched him his clothes, Remus could recognize that wolf everywhere, her eyes were grey and her snout had a little white on the front.

He got dressed and started to walk to the castle, the metamorphmagus trailing behind, wagging her tail.

"Why don't you change love?" He asked her. She just shook her head, he smiled and continue walking to his room, Cassiopeia decided to check on the DADA classroom.

As soon as the wolf entered the classroom, students screamed and shrieked in fear. Severus, realizing that was Cassiopeia, smirked and began his lesson.

"Can someone tell me the difference between an animagus and a werewolf?" Students averted their eyes from the black animal and stared at the Professor.

Hermione raised her hand like always, and Snape pointed at her. "An animagus is a wizard that changes into an animal at will, a werewolf, has no choice in the full moons. "

Then, Cassiopeia changed into herself and smirked at the gasps from the students. "That's right Ms. Granger, ten points to Gryffindor"

"Are you an animagus?" Asked Dean Thomas, a Gryffindor.

"Oh no, I'm a metamorphmagus" she said.

"They can change their appearance at will, shape shift into anything" said Hermione with awe.

Cassiopeia nodded, and as she was about to speak, Severus interrupted. "Excuse me, but I believe I'm the substitute for now" he glared at her.

"Oh Severus, forgive me, but Dumbledore sent me to... observe" she said smirking. He hated that smirk, that Black smirk everyone of the family shared. He had became used to it with Bella, but it made him uneasy.

"Very well, you'll have to do an essay about the difference between an animagus and a werewolf, I want it in three days on my desk" he said and left.

"You can change into other animals?" Asked Ron with a grin that made him look stupid.

"Yes Ronald, I can, but I will save my skills for your metamorphmagus class" she smiled and dismissed the class, returning to his beloved.

"Harry! She's a bloody metamorphmagus!" Ron shrieked after DADA. He really couldn't see anything wrong with the girl, he found her amazing.

"Yeah, that makes her more suspicious, she's hiding something, I just know."

"I don't know Harry, she seems... normal?" Hermione suggested, but that was the reason Harry found her suspicious, she was to normal for his taste. He believed she was up to something, and he was gonna find out what that was. Tonight.
