Thank you! I'm really glad you liked it - and found it believable too. This was my first attempt at writing Andromeda, so I'm glad I got her character alright.

From OotP, Sirius' childhood seems to be something that lingered with him. Of course, it might have been just because he was trapped in Grimmauld Place at the time, but still. So I tried to base this from that - and the fact that Sirius and Andromeda both tried to turn their backs on their family in different ways, giving them something in common.
