Bree showed the turtles all the memes she had screenshotted, she showed Donnie her mediocre bō-Jitsu, raved to Leo about little siblings, joked with Mikey, and discussed fighting techniques with Ralph, and overall tried to postpone the inevitable: their departure. Suddenly, the portal above Bree's window began to falter. No one had noticed that it hadn't closed up like it normally did.

"Guys, we gotta go before it's too late," Leo warned, his voice deep and gravely from his epic battle with Shredder that put him in a three-month coma. The three were reluctant but understood.

"What about me?" Bree asked, not wanting to be sidelined like April and Casey were so often.

The turtles exchanged a look. Ralph began to speak.

"Listen, kid, this has been nice and all but you can't come. Your not a ninja. You're not prepared."

Donnie picked up the speech. "No offense, but your bō-Jitsu is terrible-"

"Uh, OFFENSE TAKEN!!" Bree interrupted, practically yelling, but she knew Donnie had a point.

"Plus, we have no idea how your cells will react to the portal. I still don't know the physics behind it all. Does it work for us because we're mutants, but then again, April and Casey can pass through easily, so maybe it has something to do with-"

"UUHHHH!! Okay, dude! We get it!" Mikey intervened. He turned to Bree. "Sorry dudette, but you can't come. It's comforting to know that there are humans out there who appreciate all we do, but if something happened to you, I know I wouldn't be able to forgive myself. Sorry." Everyone had tears in their eyes by now.

"Okay, fine. I'll stay." Bree promised, but her fingers were crossed behind her back. Mikey gave her one big bear hug before following his brothers.

Once the last of Mikey had disappeared into the portal, which was now mutagen green, Bree leaped through.

Once the room was empty, the portal flickered once, twice, then shut off, the triangle that projected it thumped onto the pink comforter, just as the turtles had.
