![[S3E22] Mason Cable Choices](http://www.knightriderarchives.com/images/next_ep.jpg "Next Season")
Watch the high-stakes conflict between MacGyver and his new rival Mason in the Season 3 finale:
Played by Peter Weller, Elliot Mason is a "next-level smart" villain whose motives are deeply personal.
Mac attempts to save the falling elevator by connecting it to an adjacent one. In physics, this creates an Atwood Machine , where two masses connected by a string over a pulley accelerate much slower than free-fall.
Mason uses similar problem-solving skills for destructive ends, such as a motorized cable cutter and hydrochloric acid used to weaken building support pillars.
