I found my theme for Dragon*Con - Meeting people accidentally and realising it MUCH later.
Exhibit A: Snapping a pic of Ruby Rocket as zombie Scarlet Witch and not realising it was her until I got a good look at the photo later, and by then she was gone.
Exhibit B: I was looking to meet the Polaris I saw last year, who's also done a lot of other awesome costumes, but never saw her. But that was her as zombie MJ I was taking pictures of all Friday night!
Exhibit C: And this should amuse roguesamus...the person who took our photo in the dealer area? Is an old friend of mine and I never realised it.
