At first, when he produces the bottle of green liquid, she wants to make a joke about Derek getting her high, but for what might be the first time a very long time, Kate keeps her mouth shut. Instead she reaches for it, looking at the way the sun hits the liquid inside, and she lets him explain.

Then her eyes widen, her gaze flicking from the bottle to Derek and then back again as she processes what he's just told her. It's kind of a huge thing. In reality, Kate has never been truly normal, not by the standards most people use to define the word, not with her crazy ass family, but when it comes to Darrow, she's pretty much as boring as they come. No powers, no abilities to turn into things, no weird world saving abilities, and definitely no monsters trying to destroy her world. Totally normal. But what he's offering her is a chance to be something else, even for just a little while.

Something like him.

"No fucking kidding?" she asks, just to be sure. "I'd be for real a wolf? But like... still me?"
