Shaking Marcus

So I wonder, was I the only one who felt like shaking Marcus? Sooooo much could have been avoided if he had just talked to his parents. I understand that he was traumatized by Gitmo on the Bay and if he had told them, the X-net probably wouldn't have happened the way it did. But he let his best friend's parents think their son was dead. For a long time. This just doesn't sit well with me.
