Something tells me that Elis does know that Tim is right... but she doesn't want him to be right. I think she might be trying to convince herself more than she's trying to convince Tim.
Or maybe she already has accepted her own alternate universe and she really IS trying to get Tim to believe in it.
I don't know... it's all very interesting, either way.
I'm so happy I clicked on this link a couple months ago.
This comic has really touched a part of me that I didn't remember I'm had and I'm glad there's something like this out here and not just those blasted VG comics with the cheap jokes that are everywhere.
