I didn't really think about Severus's sister being the victim -- I thought she would be away from home at her in-laws' if Severus was keeping his niece...unless they both foresaw danger and felt she'd be best protected at Hogwarts. I had so wanted to see Severus around his sister, even if only by Owl correspondence. Now he will most likely become probable legal guardian (is there a British term for this?) of Ophidia. Will the earth tilt off of its axis? ;D
I can't remember Severus blowing his cover...would someone please point me in the right direction if it's from a past post?
