I can already tell that this part of the storyline is going to involve a LOT of streamlining of what I initially write for Ellen.
I didn't want Ellen to have full-on stage fright (or the RPG equivalent), as that's not really what her story here is about, and it would step on Nanase's toes (she called dibs, darn it!).
It didn't feel right for Ellen to be immediately comfortable acting this out in front of everyone, however, and her doing this is what made sense to me.
