My back shoots up straight when I realize where his words are leading to. I know I can try insisting what happened was my fault and beg him not to get anyone else involved. But I also know all of it will be useless.
 
 Everyone knows that the Devil's appetite for vengeance is never-ending, but if these days of talking to him on the phone have taught me anything worthwhile about him...
 
 "How about a game?" I force myself to croak out.
 
 Several moments of silence pass before the Devil gives me his answer.
 
 Go on.
 
 I sag in relief against the back of the tub. I know this doesn't guarantee anything, but at least he's willing to give me a chance to change my mind.
 
 "Heads, you won't do anything to Tara—-"
 
 Unacceptable.
 
 "Because I'll be the one extracting revenge for myself," I manage to improvise without missing a beat.
 
 If you break your word, you understand that I'll have to punish you as well—-
 
 "I—-" I almost say 'I do' out of habit but catch myself in time. "—-understand."
 
 And the other girl's punishment shall also be more severe—-
 
 "What? Wait—-"
 
 —-than what I originally intended?
 
 "But—-"
 
 You didn't really expect to play a game with me and be able to lay down the rules—-
 
 I actually did, idiot that I am.
 
 Did you?
 
 Rather than admit to my stupidity, I think I'm going to change the subject instead.
 
 "Can we talk about what will happen if I flip tails?"
 
 Proceed.
 
 "If I flip tails,wewill decide together on what to do with Tara—-" I hold my breath and wait for the Devil to protest against this.
 
 Go on.
 
 Phew.
 
 "But I'll also owe you another favor in return—-"
 
 Flip the coin then.
 
 "But I haven't—-"
 
 Don't wait for me to change my mind.
 
 Oh crap.
 
 "Let me just get out of the bath and find a quarter—-"
