Is The Irrational New Tonight? (March 11, 2025)
Which mind-boggling puzzle will Mercer solve next? Watch Season 2 of The Irrational on Tuesdays on NBC.
Season 2 of The Irrational is back with new episodes, and Alec Mercer (Jesse L. Martin) has been taken on a wild ride.
From life-saving rescue missions to mystifying crime scenes, Mercer hasn't had much time to rest as the chaos continues on Season 2 of The Irrational. Luckily, Mercer has had some backup along the way. Between his steadfast girlfriend Rose Dinshaw (Karen David) and his tech-savvy sister Kylie (Travina Springer), Mercer has all the support he needs to stay whipsmart for whatever case he faces next. The human mind is a mystifying place, but we can always rely on Mercer to crack the case.
"There are so many possibilities when it comes to just concentrating on how we think and how we behave," Martin told Collider. "Mental health is a big topic on everybody's platforms these days, and our show explores it, certainly in a scripted context, but in so many different ways with so many different people. The more interesting actors we get in, the more that behavior surfaces... There are so many places to get creative. There are so many stories that can get told when you're just talking about behavior, in general."

"We are so lucky and privileged to have Jesse Martin playing the role of Alec," The Irrational showrunner Arika Lisanne Mittman told NBC Insider. "When I first wrote this character, there was a character I wrote on paper, and there's what Jesse brought to it, and those two things put together have just created magic, and I'm so grateful to have him. He's wonderful to work with. He's really a gift to all of us."
