On the latest episode of "Limitless," titled "Close Encounters," Brian (Jake McDorman) gets into a heated debate with ... himself over "this whole avoiding Rebecca (Jennifer Carpenter) thing."

"Dude, what am I supposed to do?!" says NZT Brian to his Funyuns-eating alter ego in Zap2it's exclusive sneak peek. "You know when I'm around her, all I can think about is that I know that Sands (Colin Salmon) murdered her dad. That the person who killed him is the same one keeping me alive. But can I tell her that?"

"No," says Funyuns Brian, "because that would mean you would have to tell Rebecca that you were Senator Morra's (Bradley Cooper) mole in the FBI, which would mean losing the enzyme, your immunity ... and even if you found some way to dodge all that, you'd have to go back to being just Brian."

"Hey!" says NZT Brian.

To find out what NZT Brian decides to do, tune in to "Limitless" Tuesday, March 8 at 10 p.m. ET/PT on CBS.
