Both beer and wine are consumed in the same night. One character very quickly drinks half a bottle of wine. Characters slur their words and have droopy eyelids.
A character is portrayed in a way that it seems like he could be mentally ill (in the stereotypical horror movie way) and is about to be violent, but trying to avoid spoilers I'd still say no given the way that part plays out. But it might still be upsetting all the same.
