for some reason i can't seem to remember that dude :\
any scene in particular where he showed up?
Two times in particular. He is the guy that was guarding the building and reading A Brief history of Time in the episode where Kate, Sawyer, and Alex all show up to break CUH-CUH-CUH-Carl out of room 23 (the brainwashing room), and the guy that gets shot by Claire at the end of this episode.
