I love Andrei and Nikokai - AND Vanya.
That is why I named Mishka with a Russian name too!! My parents sometimes call him Vanka (it's a version on Vanya ~ we all speak russian)
Anyway Aly you SHOULD adopt them out together if they're bonded but if for some reason you don't or
cannot - please, please keep me in mind - I would love to take either, I just couldn't take both (not that I wouldn't LOVE to though!)
