Huh. Interesting happenings.
I kind of noticed the tone of ability-or-lack-thereof-is-not-a-clue what with Joey kicking Griffen (he has nothing but his spring, so that must mean the bouncer literally bounced). Also, did Steve and Quack make Crack snort gender-bending gas? After the gassing, Crack is suddenly a him.
Nobody seems particularly suspicious here. Only Iris, and I don't think the reaper would be that careless. The most suspicious one was Rick, who obviously is the Reaper's accomplice, and Ray seems to be pulling strings on Netrizen here, so I wouldn't be surprised if he were in cahoots as well.
Seeing as I can't vote somebody due to suspicion, I'd have to make a character-based vote, so I vote Brandy. At least two other pokémon died back there, and all she cares about is selling her book. I'd almost suspect she was the reaper due to not showing any sort of worry whatsoever. At least other characters like Crack and Maya have the excuse of being a little funny in the head, but Brandy? One would think she would show more concern than this.
