Tony is no one important. Just a random guy with a random hard drive. We'll probably never know nor do we need to.
I wonder if this was just a stall tactic, like Juan said, and the guy is going to claim he made a mistake and grabbed the wrong hard drive and does have Travis' mirror image?
I'd like to know who Tony is. And, what " guy grabbed the wrong HD." If that was the case. Assumption for now.
