Hi, I'm Hannah and I play Eileen and Frank Sunderland. (And also Midvalley, over on the other side.) Frank and Eileen are going to freak and Walter will probably remind Midvalley way too much of Legato.
Frank doesn't know everything that happened to Henry and Eileen in-game, but he does know the basic issues and feels some serious guilt about the whole mess, including baby Walter ending up at Wish House in the first place -- which he has felt ever since rumors started about Wish House. (I have this... extensive fanon about Frank, which is probably kind of sad.)
I'm on the list they posted but I can be reached over AIM at rosehiptea and at yosefraptor@yahoo.com.
Welcome, I'm looking forward to being terrified by Walter!
