On Saturday of Ottawa ComicCon, we met the ninth Doctor himself, Christopher Eccleston! (I wish Pegasus had been with us, but Saturday was too long a day for him.)
I was too flustered to come up with anything to say, so we just told him that our kids had watched his episodes and loved them.
I talked to this cosplayer about the costume, and I’m not 100% sure I caught it all, but I think she said that she’s not a princess, but that she’s from an obscure fairy tale from Germany?
