Something that's been bothering me

Who was this guy, that appears in the second episode of season 1. Obviously he was a monster, but why did he ask Julie if she remembered him, and it actually looked like she recognised him, but didn't know from where. Was this the first clue as to the whole time-traveling ability, that we see her have in season 3, or was he just trying to play with her mind in order to kill her.
