It was entirely possible that he was one of the aforementioned liars, since he could think of a few things that he'd covered up or lied about in the past, but why did he have to tell these people about it? And what if he wasn't one of them, but spilled a secret anyway? There was really nothing that bad that he'd done... was there?
"Peter's the one with wounded pride," he muttered, half to himself. "And I'm probably the one who lives in constant fear." Unless John or Iris had their very own personal stalker, which he doubted. It would make sense for all of them to confide in one another, but that would only work if everyone was willing. "This is like some... messed-up trust exercise," he said, his voice a little louder. "If Peter wants to go first, then I'll go second, just in case." He moved over to the boxes, trying and failing to open them. Confide - would that open them? "I don't think it would hurt if we all confided something." He wasn't positive about that, but he didn't want to be the one pointing the finger at anyone else.
