I'm kind of making Venvolar's rules up as I go along, so if you guys feel something I do doesn't make sense, feel free to let me know
In this case I figure that Chelsea, as the soul-in-control (power chord) at that moment, had all but given Mar permission, but Venvolar had not. Chelsea is still a part of the Venvolar... collective... thing. The 'boy' Venvolar stepped back into control before Mar could get ahold of Chelsea, locking her in again.
Honestly I wasn't sure what happened. Her soul got sucked out? Would that be better or worse?
Haha... hmm... I don't know exactly what a soul goes through when stored by Mar, but I know there's very little chance of it being a desirable position to be in. Then again, neither is being 'stored' by Venvolar.
I like that 'puppet' take on Ike, Chad, whether you decide to use that or not. He's a very intriguing character to me.
Have I mentioned that Venvolar creeps me way the hell out? I will make up for him slightly with my next character, promise. I just had an especially dark moment of inspiration with him.
