Stiles' eyes bug out a little, but he's secretly relieved that she has something on under her clothes. He gets clothes thrown at him and he bundles them all into a tight ball in his lap, clutching them. He's equal parts confused and intrigued, because what the hell is she doing.

If she could knock thugs around, why wait until now to do it?

He gets his answer when her face shoots out, and Stiles can't help it - he backs up against the dumpster a little, completely shocked even after all he's seen. Then his mind runs into overdrive, of course.

Is she something like Derek, Scott and the others? She doesn't look like a wolf, though, very quickly, and he wonders if it's something else. If she's something like a changeling from Star Trek, like Odo.

The batarians are shouting about them being in the alley but Stiles' saucer-sized eyes are focused on the morphed Rachel.

He hears her voice in his head and that makes his jaw, which dropped when she started, snap back up.

"I'm not freaking out," he says, but his voice cracks once. Then he shakes his head and gives her a tight grin. "Knock 'em out, tiger."
