Re: Arrivals. Lance showed up with the majority of the Voltron folks. :]
Loki was there with Ben. I'm lazy, so just... imagine she was in a nice green dress.
Nikolai was there with Buffy/Buffy's group/Mal/Alina. Standard tux for him~
And it seems like Rocket might be there, but he's not dressed up like everyone. He put on a plain t-shirt and clip-on bowtie. That's as good as you people get.
