I loved this. I love that Petunia was the one scolding Lily to behave properly, and Lily wishing they go back to how they were (similar to how Merida remembered how her mother was when she was younger)

I love that the Marauders were in their Animagus forms here (as Shapeshifters instead) and that Peter bit the Werewolf's paw. Brave for a little rat!

Oh I laughed at how you described James as a really weird stag. I think that was just my favourite bit.

This was really enjoyable. I love it!
