Remus can play piano. I've no idea where this came from, it just popped into my head and it somehow makes sense to me. His piano playing will go one of two ways.

Way number 1: This is what happens mostly. He'll conjure his piano with all his piano books, select a book, close said book and then play the piano with that book, causing an annoying racket. He loves to do this to annoy other Sides, especially Roman.

Or way number 2: This is when he is in the mood to actually play something. He'll conjure his piano and piano books, yadda yadda and then he'll just sit down and flipping play a Beethoven song or the entire score from Hamilton. Often, he does this to make the other Sides confused.

I think that this came from the fact that Remus is Creativity too and does have some artistc temprement deep, deep, deep..... very, very far down inside him.
