Yikes! Cabe Risks His Life on Scorpion's Harrowing Midseason Finale

Team Scorpion is here to save the (holi)day!

OnScorpion's midseason finale on Monday (9/8c, CBS), the gang is called in when a dam starts to crack and threatens to flood the town below. And true to his Terminator 2 roots, Robert Patrick proves that he's still a badass in an insane action scene that may have cowed lesser mortals.

"Robert Patrick does this amazing stunt that's basically crawling down the face of the dam in a harness," executive producer Nicholas Wootton tells TVGuide.com. "It's really harrowing; it's like a 200-foot dam face that's really vertical. He's strapped into it, trying to fix this dam."

But Cabe (Patrick) isn't the only one on the team risking their neck. "We also had one sequence where we're clearing out a turnbine that's been causing this flooding and cracking of this dam," Wootton adds. "It's an interior shot with a lot of water where ultimately Happy (Jadyn Wong) gets sucked into it and into an outflow pipe and is going toward the turbine."

Despite Happy's water-logged plight and the story line, the production team was very mindful about not using a lot of water on set. "There's a major drought in the western United States, especially the southwest, and we just couldn't use that water," executive producer Nick Santora says. "We didn't feel that it was responsible." Instead, production used CGI and reclaimed and recycled water for most of the rain shots and Happy's turbine stunt.
