The magic pours out one is awesome, but I've mentioned this earlier, so I'll go with it.
Dan:

I had forgotten how long Chris's chapter was. Anyway, I don't feel like clicking through all of Dan's, which I don't remember well, so I'm just gonna go with this.

He really was being a pansy-ass mama's boy.
Stephenie:

She's has much too much proclivity toward being hurt, both physically and emotionally.
Seymour:

Not much to pick from here since Seymour doesn't really do anything and the MMO scenes are mostly just the same character pose over and over, so I'm going to go with this because it's far too awesome to ignore, even if it is technically post-Seymour.
edit - also, wow. We're actually up to over 550 panels at this point, some of which aren't mere panels. This has been a pretty long ride already, and it feels in some ways like we're only getting started.
