I just thought of something. At this point in the story are Marcella and Andriel the only ones that know that Kristi is Snape's daughter? I can't remember now.
Emma: Yeah, I think they are. That's a very good point actually Kris. Let me ask you, does Kristi plan on coming out about it and her death and being honest, or is she going to keep her dad secret? Because obviously she's going to be a bit torn about him being in Azkaban and people will grow suspicious as she's supposedly only his student. <s>Myself</s> Marcella, Archie and Snape are the only ones who thought she died so that really isn't a problem.
Well, now that you mention it; I don't think Kristi would come clean with everyone. I think she'll just try to keep it secret and let people have their suspicions. It's more fun that way .
