‘Limitless’ Clip: Jake McDorman Uses Barney-Like Friend to Cope with Murder (Exclusive Video)

New episode of CBS series airs on Jan. 19

Barney the Dinosaur did a lot for kids, but he never helped solve a murder.

In this week’s episode of “Limitless,” Brian (Jake McDorman) embarks on his first FBI field assignment when he travels to Quantico to help catch a serial killer.

But when he encounters a bloody crime scene, Brian’s mind uses a Barney-like character from his childhood to help him cope with the brutality.

When the FBI dubs the killer The Marrying Man due to his habit of removing a victim’s ring finger, Brian and his childhood friend come up with a less sinister moniker: Mr. Pralines and Cream.

However, the trip takes a negative turn when Brian realizes the man he’s working with may have put an innocent person away.

Meanwhile, Brian tries to stay one step ahead of Rebecca (Jennifer Carpenter) as she investigates Sen.  Morra (Bradley Cooper) @LimitlessCBS Clip.

“Limitless” airs Jan. 19 at 10 p.m./9c on CBS.
