James Savage's eyes are too orange to be considered "brown", and Criminal Case's werewolves have yellow, if not orange, eyes when in werewolf form, ergo, James must be a werewolf! Also, rumors of him being a werewolf could play into his "dangerous hunter" reputation he garnered in the first season.
