I meant to do the whole group but this has been sitting in my drafts forever, so I’ll share it now and update later! I want to see everyone else’s ideas :)

Odd: Ca Va? by VK Blanka

Ulrich: Punching Bag by Palaye Royale

I'm Still Here (Jim's Theme) by John Rzeznik

Sissi is a complicated one! I think she's a great character and definitely gets painted unfairly like you've already said.

I also think she really had/has potential to be an asset to the group!

It's hard being young though. Ulrich sort of seems to see her as an annoying little sister? He hates her hanging around, but he also doesn't want anything bad to happen to her. Teasing and pranks seem to be fine, just not like, death or serious injuries.

I totally think she could join the group eventually if she just chilled out. As much as I love to pair William with Sissi (talk about matching each other's freak), I also think there's a lot of potential with Odd (or something fun like Brynja tbh) I'd love to see that get explored more too!

Anyway, that wasn't really a question but I'm glad you shared. I hope my ramblings were what you were looking for :)
