The older McComb specifically warns his younger self that they must not touch because the same matter cannot occupy the same space, then kills Parker. Fielding turns on Walker, revealing she works for McComb. After a shootout with McComb's henchmen, Fielding is wounded and Walker escapes back to 2004.
