Tbh I'm wondering if something bad happens to his mom or sister, or someone threatens them or something. He doesn't seem to be running away from something, he seems scared or worried or angry, like he's running to do something.
as far as i know, his mom and sister haven’t been cast, which immediately nixes the idea of something happening to them in my mind. if something were to have happened to them one) jug definitely would leave town and two) betty, archie, and veronica likely would have gone after him. if you just found out your friend’s family had been hurt or threatened, you wouldn’t let them walk to the bus station alone.
jughead definitely looks like he’s rushing out of the school to me
with betty, veronica, and archie on his heels
looking at the pictures, it seems to me, he must stop at the bottom of the stairs and say something to them
he then walks away (i feel like if there had been an emergency, he wouldn’t have stopped at all and wouldn’t have slowed his pace on the sidewalk)–
leaving the others behind; who also look upset
or at least betty does. archie and veronica have more concerned/surprised looks on their faces
and let me just say, i still can’t believe archie is wearing jeans to homecoming. who does he think he is?
