In the Limitless episode “Sands, Agent of Morra,” henchman Sands (Colin Salmon) needs the help of Brian Finch (Jake McDorman). But no one, especially Sands’ boss Senator Morra (Bradley Cooper), can know about the mission. Sands’ past catches us with him and he finds himself seriously wounded. When he shows up at Brian’s door impaled, Brian’s sister Rachel looks like she’s going to either faint or throw up. When FBI comes looking for Brian, it’s up to Rachel to cover for her big brother.
