Hogwarts-Alive AU

Basically, in this AU, the marauders and the rest are alive, and yes, that’s includes Lily Potter and James Potter (yesssss). Minerva McGonagall is on leave for the entire school year, so she’s asked James to teach Transfiguration and also be temporary head of Gryffindor house. James is sitting in the carriage with the golden trio (Harry Potter, Ron Weasley, Hermione Granger) and they are talking excitedly to James (User). No voice, or else..
