Original: A meteor impact throws both Ratchet and Clank off of the platform; Clank manages to grab onto the ledge and catch Ratchet, but the strain of supporting Ratchet's weight causes heavy damage to Clank's arm. Ratchet offers to repair Clank, and as the game ends they walk off together as a team.
Simplified: Clank fixes Ratchet's ship, so that Ratchet will help him.
