I was frustrated that he didn't at least try to read Adam's mind a little to confirm or deny Victoria's accusation that Adam was going to release the virus.

This was, in my opinion, the biggest plot hole of the show thus far. Peter remembers his abilities, remembers how to use them, but doesn't think to read Adam's mind at any point? He just blindly trusts this guy? He didn't trust his brother last season. It really doesn't sit well with me.
