The Marauders may be confused as to exactly which version of 1970s Hogwarts they are currently in, but even that cannot prevent them from wreaking havoc. Special guest appearances by Lily Evans, the Mirror of Erised, and Remus Lupin's temper.

Neville Longbottom decides that he hates family reunions. And picnics. And ponds. And Dugbogs. And Grindylows. And life in general.
