[ Derek Hale is far from somewhat functional. Letting dreams be dreams, however, Derek continues to spread the fucking bullshit lie that he understands how to behave like a normal human normal earth person from earth by picking up Jughead's invitation to leave and actually being polite enough to act on it. After taking back his phone, he rolls his shoulders, cracks his neck, generally gets himself ready for the rooftop parkour he's about to engage in so as to get home without having to take the bus, then strides back to the open window. ]

Pick up your phone if I call you. If you don't, I'm coming back through the window. [ He points one finger at Jughead, eyebrows raised. ] If you change the locks, I'll break the glass. That's gonna be on you.

[ He points at his eyes, putting one leg out the window. Points at Jughead's eyes. ]

I'll be in touch. [ ... ] You can be in touch, too. If you want to be. [ He lowers his arm. Visibly struggles to think of a way to say goodbye, then quite clearly realizes he doesn't give enough of a shit to actually do it. Settles both stoically and majestically on arching his eyebrows one more time before bailing out into the darkness, the sound of boots hitting bricks the only sound of him left as he scales the outside wall like the absolute worst version of Spiderman. Go to sleep, Jughead. ]
