Generally speaking psycho hellgods aren't to be trusted.
Well, remember how it took a mystical weapon to kill Caleb last time? We don't exactly have one of those, but we do have a crazy hell god, close enough right? Caleb wants the Slayers and has offered Peter a trade. Glory wants someone who can open dimensions. Now, she's fought B, but never me before. So, if Caleb and Glory are both tricked into coming after me, what if they fought each other instead? While we watch with popcorn.
