Yeah.... oooh, maybe he hears their heartbeat and catches them in a "lie" of some kind, and he doesn't call them on it, because he knows they're lying/anxious but doesn't know about WHAT yet, and he's trying not to panic even though he feels like the rug has been pulled out underneath him (because once they all got past the posturing Matt can give them credit for being pretty blunt/honest with him). So then he listens in on their conversation and hears (whatever) and and and his brain just kind of needs to do a reboot because they lied (what did you expect, Matt?) and they used him (stupid stupid STUPID) and they tricked him into thinking they actually cared and now he's put everyone in danger and - (hold power button to shut down and restart) *beep*
