Not that Zach even knows or understands all of that. I think he just seems overwhelmed by the whole post-Big Brother experience and has wanted to get some space and some perspective on things. His parents even took his brother out of school this week to hang out with Zach.
Zach has been bombarded with fans and I don't think he's loving that. At least, not right now. I think he's finding out how he was portrayed on television and is coming to terms with that. He's not even going to watch the show for awhile, he says, but does plan to start tweeting and instagramming soon.
He does look healthy, though, and is very gracious when speaking about his all of his cast mates. Even Victoria.
