Scorpion is getting fishy.

'Scorpion ' Season 2: Prepare To Meet Ray; Walter's Community Service Pal To Shake Up The Team

The CBS drama is already shooting its third episode for season 2, and the creative mind behind the "Fish Filet" has been churning out teasers since filming began in Late July.

"Prep done, guided by our peerless director @ADAMMOAR aka Omar Madha," writer Paul Grellong tweeted last week. "Ep 203 shoots Monday. On my honor, #TeamScorpion... you're gonna plotz."

In other words, Los Angeles' resident geniuses and their devote fans should be prepared to collapse with excitement.

Once Walter, Happy, Toby, and Sylvester pick themselves up off the ground however, they should prepare to rack up a serious gas bill. According to Grellong's behind-the-scenes photos, Cabe's (Robert Patrick) team will head from the Port of Los Angeles to the woods via an incredibly imposing bunker (see photos below).

The episode's title reminds me distinctly of Friday night dinners, however, it's probably safe to bet Walter's crew find plenty of answers down at the docks.

Scorpion will open season 2 with "Satellite of Love" before moving into "Cuba Libre," "Fish Filet," and "Robots." The series will return to CBS on Sept. 21 at 9 p.m. ET.
