I was just really struck, on finishing watching the series, with how much I wanted to see these two together in the aftermath? Since they were each the closest person to one or other of the two vanished magicians, I really wanted to see them bonding over the loss and uncertainty. (Although I'd prefer it if the Childermass/Norrell side of things wasn't romantic, exactly, I don't mind too much either way.)

I just want some very domestic hurt/comfort and moments of tenderness that turn into falling in love.

(Bonus points if Arabella ends up picking up (or just revealing that she actually already has) a bit of art magic, and Childermass is very appreciative of this)
