Totally. I think he was doing it because he didn't want to have to blurt out the REAL reason he didn't want to go. I also liked the idea that if something was bothering him, other than all the conspiracies and stuff, he'd be less willing to share it.

I can't believe they haven't brought that back up. I've always wondered why. We know Brennan and Goodman don't know and the others have sworn they wouldn't say anything but still, it'd be an intersting episode.
