On the Bradley Cooper-produced TV series Limitless, the protagonist Brian Finch (Jake McDorman) gets a little tangled up in the personal life of FBI Agent Rebecca Harris (Jennifer Carpenter). While taking NZT, Finch discovers a secret about Rebecca’s late drug addict father but doesn’t want to tell her because it could get Finch into legal trouble. And then he meets Rebecca’s secret FBI boyfriend, Agent Casey Rooks, who teaches Finch how to physically defend himself while out in the field.
FBI Agent Casey Rooks is portrayed by Desmond Harrington. He’s best known for his roles on The Astronaut Wives Club (Alan Shepard), Dexter (Det. Joey Quinn), Gossip Girl (Jack Bass) and Rescue Me (Troy). Limitless airs Tuesdays at 10pm on CBS.
