Sirius as one of those people who has to move to help himself think can be derived from the cave scene in GoF, right? Still, I catch myself hoping that extrapolations like yours are not the only ones you can accept when reading fic.

What you say about realism, as well as about the presence of hope and damage sounds like my approach to Remus and Sirius’s story. My humour is just more quiet.

Glad I friended you, I’ll be looking forward to more from you.
