Just watched this week's Defying Gravity, "Fear."
I loved Donner's flashback Halloween costume, and that it was a 20th century reference. Also, he looked adorable. But I do wish in the present-day arc, more people had dressed up. I'm with Wass - Halloween without costumes sucks.
(By the way, Wass is so into Paula. How obvious is this?)
On a related note: Nadia is kind of a bitch. Hope that's not a spoiler for anybody. :P
