"Hel... hello." Jughead says as you sit down across from him.

He doesn't say it out loud, but he's disappointed. He asked you out only because you were dressed as a hamburger, not because it was... you. Jughead had imagined a whole future next to that giant burger, seeing you outside of the burger suit was charmless, he lost the interest immediately. So he's texting Archie, Kevin and even Moose for help in the most dissimulate way he could.
