I don't go to Detour because I'm not into Anime, but I love the idea of panels where the people are essentially role playing characters.

There was a proposed panel at Convergence some years back that was the "Death Eater Panel" that was supposedly going to be DEs reminiscing about the good old days with the Dark Lord and talking about what they've been up to since his fall. I signed up for it because HOW FUN WOULD THAT BE? But apparently no one else did, because the panel wasn't held.
