Hee, well, who's more present to Wendy than her own alternative self? Heh, yeah, that was a pun opportunity I don't think Wendy herself would have missed.

I'd say Non-Mirror!Wendy would be the only person Mirror!Wendy would be comfortable having girl talk with. Mostly because...

... She doesn't know anybody but West! Seriously, I had to collapse Cratchit, Scrooge's nephew (Freddy?), and Tiny Tim all into one character because there's just plain no one else Wendy would actually talk to or even give a crap about. She's actually worse off than Scrooge himself, when you think about it.
