Wounded, Joker catches up to Cullen and warns him about the swamp. As the posse led by humane Sheriff Max Muller gets close, the escapees can hear the dogs on their trail. They also hear a train whistle and run toward it. Cullen catches up to the train and jumps aboard. In this pivotal scene, Joker is running alongside, desperately trying to catch up. Cullen calls to Joker, urging him to run faster, and holds out his hand for Joker to catch hold. Their hands clasp but Cullen is unable to pull Joker aboard. It is unclear whether Joker accidentally pulls Cullen from the train or Cullen deliberately leaps free, unwilling to leave his friend behind.
