The latest episode of "Limitless" will expose the trauma faced by Brian Finch (Jake McDorman). He will unravel while leading his double life as an FBI informant and NZT-48 user. This will put Rebecca Harris (Jennifer Carpenter) and the rest of her team in a quandry in Season 1 episode 19 titled "A Dog's Breakfast."

Senator Morra (Bradley Cooper) makes contact with Brian and his timing couldn't be worse. Brian is put on 24 hour surveillance by the FBI and find footage of him meeting a very suspicious person. At this point, Rebecca begins to panic.

In the promo released on Entertainment Weekly, Rebecca sees Finch with+ Jarrod Sands (Colin Salmon) and wonders what might have transpired between the two. She remains ambiguous when Mike and Ike ask her if Finch could perhaps be selling FBI's secrets to Senator Morra or the Russians.

She says, "You guys if he is selling confidential information to senators or anyone else, we owe it to ourselves to get in front of it. If he isn't, then we owe it to Brian."

In any case, this new development in the story doesn't indicate good news for Finch, who has been desperate to find acceptance from his new family. Rebecca's next move remains to be seen.

Season 1 episode 19's synopsis (via TV Guide) reads:

Brian's double life unravels when Senator Morra makes contact just as Brian's placed under 24-hour surveillance by the FBI following his rogue trip to Russia. And the possibility of his connection to Morra being exposed seems even greater when Mike and Ike reveal to an already suspicious Rebecca that Brian had an off-book interaction with Morra's henchman Sands.

"Limitless" Season 20 episode 19 airs Tuesday, March 22, at 10 p.m. on CBS. You can live-stream the episode via CBS All Access.
