Mark Valley, who plays the traitorous and ill-fated FBI agent John Scott on Fox's sci-fi drama Fringe, promised closure to his storyline in February episodes.  "They do answer some questions that have been lingering in my mind, like who he's been working for, exactly," Valley said in a conference call with reporters on Friday. "It sort of confirms the verity or the truth of his feelings toward Olivia [Anna Torv]."
