I tend to write Remus as a stubborn little git. He's slow to make his mind up but once he has he's politely immovable.

I'm very fond of Tonks and I've always liked the ship but it really took me by surprise. OotP convinced me that JKR was deliberately writing Remus and Sirius in a way which could be read on several levels. I certainly think there are plausible ways to work out how that relationship happened without making either character behave despicably.

I'm glad you like Andromeda. She's great fun.

Thanks for the comment :)
