I get that. But to me it makes more sense to retcon her, since she hasn't really had any impact at all on any of the characters yet. Much easier to reintroduce Christine as a "new" character than have to work around her disappearing. But it's up to you and the rest of the group.

Oh I see what you're saying, yeah I suppose we could just retro-actively act as though she wasn't there. She didn't make any real interactions yet.
