Ok, so my Angel just switched playbooks to Brainer, and took in-brain puppet strings as one of her moves. This is awesome, because it means she'll be doing even more brain fuckery, but I don't quite get how the move is supposed to work.
First off, what sorts of commands are acceptable? Her first use of it was a pretty open-ended one, timewise ("don't leave the building"). At what point does that command become "fulfilled"? Or is that not an acceptable command, because it doesn't have an obvious criterion for fulfillment?
Secondly, what happens if they don't fulfill the command? Does the brainer get the right to brainfry them for the rest of their life, or is there some sort of time limit?
The specific situation: My player ("Ace") decided to command her brother, who is currently possessed by a ghost named Megan, not to leave the building. Ace later got into a situation where it made sense to have Megan around, and used Lost on her. So she came to Ace, and Ace had no reason to fry her brain. However, by the rules as written, it seems like she now has permanent leverage over Megan. She can't fulfill the command ever, so there's no way for her to use up Ace's hold. Ace can just threaten to brainfry her if she doesn't do everything she says.
That seems like it's almost certainly not intended behavior, am I missing something? If not, any suggestions for a fix?
