3x13 - Samurai Jack

Jack is directed to a deathtrap-filled labyrinth which holds a diamond that can restore him to his time. Unfortunately a master Thief also enters the labyrinth going for the item. The two of them prove equally adept in their own styles of bypassing the same traps through technology and training. The two men are forced to alternately join forces to defeat the guardian statue-robots and double-cross each other to make sure they end up with the gem. Jack helps the Thief escape who in return leaves him trapped - overwhelmed, Jack is on the verge of defeat when the Thief returns to pull him out. The two seem to come to terms...just as the diamond shatters and the Thief apparently disappears.
