I owe that bit in part to stereolightning, who pointed out yet that I didn't have a scene where Tonks either found out that Remus is a werewolf, or talked about when/how she had found out before this – but once I sat down to write it, it just seemed like she couldn't possibly react any other way, could she?

Andromeda! This is the very first I ever wrote of her, long before she became the main character of so many of my other stories. Makes me a little nostalgic. :-)
