Mm-hmm. Well, at this stage in proceedings, he hadn't actually interrogated anyone. He had attended the outer room of the interrogetion suite and done a profile on Max. There has been no on screen interrogation.

We have only seen him interact with Booth and Brennan, no other patients, and get on Hodgins' nerves. His response when offering his unsolicited help at the beginning (Boy in the Time Capsule) was to hope he was right because it would impress his girlfriend. That immaturity remains all this time later.
