In a statement, the actor said: "Over the past few months, the producers of FBI: Most Wanted and I have had discussions about my departure from the show in favor of additional creative pursuits and the transition of my character Jess LaCroix. These ongoing conversations have given us an opportunity to orchestrate a seamless and productive way for me to leave the show."

He added: "​​I wish the show, and its cast & crew, the greatest success in the future. I am grateful to have had the opportunity to play Jess; he is a good man."

FBI: Most Wanted creator Dick Wolf, meanwhile, reacted to the news by releasing his own statement reading: "We are saddened to see Julian leave. His portrayal of agent Jess LaCroix has been a key factor in the success of FBI: Most Wanted. We will miss him and we wish him the best in his next chapter."

The synopsis for the actor's last episode reads: "The team pursues an abusive man on the war path to find his ex-girlfriend, who is trying to escape him for good. Also, Jess and Sarah make plans to take their dream vacation together."

Asked how McMahon would be exiting the show, executive producer David Hudgins said to Deadline: "The episode is a combination of two things. It's a very intense episode about domestic violence, which is something we'd always wanted to do because it's such a huge problem in this country right now. It also ties in thematically with Jess' experience with Sarah's (Jan Landon) stalker, Hugh. We felt like that was an interesting additional layer to the episode. And then on top of that, we've got Jess and Sarah in a very good place, talking about going on the first vacation that Sarah has ever seen Jess take."
