A Phenomenon When You Came Along (слэш)

Stiles and Scott embark on a road trip together. This isn't a metaphor (except for how it is.)
“It’s okay, I’m good.”
“Yeah, you’re the best,” Scott replies automatically.
It’s one of their stock phrases, something they’ve said since childhood --- as natural to them as their ability to communicate through eyebrow-raises, their super-secret handshake and their unending loyalty to one another, but Stiles thought they’d retired it when they were fifteen, so he glances at Scott quickly.
“Sometimes I think we’ve forgotten how to be us and then you say something, or look at me a certain way, and it all comes back.”
