The "lines" on Matt and Ted's necks. I think this is how Mr. Bennett is "marking" the people he has found. It's too much of a coincidence that both of them were drugged, lost two days, saw the Haitian, and now have "the lines". It has to be Bennett. I still don't know whats going on with the "helix" tattoo, however.
Why Bennett would be marking everyone, I dunnos. I'm thinking that he's perhaps sticking a device to track them (so he won't lose track of them again). He shows up in a photo from the Dec episode, with Chandra. I'm fairly certain that they were working together at one point - possibly to figure out who has the metahuman gene and then to activate it. It would explain the photos on the map Chandra (and Sylar) had.
