Okay, I got two ideas for how to react to this, neither of them very good in my opinion. I eitjer have Zach give them a chance by pronouncing he's blood-starved and about to lose it, but that would break their cover. I could just have him give into his hunger and attack, but do to his condition, his powers aee greatly weakened. Should I just wait for Caits to respond with something, or go with one of my ideas.
