You’re Killing Me’s Tom Cavanagh Breaks Down Secret Wife Bombshell, Teases ‘Monstrous’ Season 2 (Exclusive)

You’re Killing Me’s season 1 finale left fans with more than one cliffhanger, including a massive roadblock in Allie and Jack’s budding romance — and a “monstrous” season 2 is already in the works.

Warning: Spoilers below from season 1, episode 6, of You’re Killing Me.

“I knew a little, which was great. I knew about it beforehand,” Tom Cavanagh, who plays detective Jack Kerrigan, exclusively told Us Weekly of the shocking romance twist that came to light during the Monday, June 22, episode of the hit Acorn TV series.

During the finale, Jack finally kissed romance author-turned-ameatur sleuth Allison “Allie” Chandler (Brooke Shields) at her and Gen Z podcaster Andrea “Andi” Walker’s (Amalia Williamson) book party.

Allie pulled away as Jack leaned in, causing him to tell her it was a “mistake” and they should just “forget” it ever happened, to which she agreed. However, Allie started to second guess her action during a restless night.

“They’re adults, right? Like, it’s Brooke Shields, they’re not kids,” Cavanagh, 62, told Us of the main characters’ road to romance. “They’ve gone through all these different iterations of romantic life [and] nothing’s going to necessarily intimidate them.”

He noted, “It’s lovely that they’re worthy opponents” and there’s a “will they, won’t they” dynamic between the two.

Fans held out hope for a “will they” moment after a drunk Allie decided to confess her feelings for Jack during the episode’s final minutes. In order to make it to Jack’s cabin, Allie had to wake Andi up from her guest house and convince her to drive, which she reluctantly did.

Once at the cabin, Allie tried and failed to have a Say Anything moment, holding her cellphone up over her head and screaming for Jack to come outside.

A mystery woman came to the door, which prompted Allie to say, “You’re not Jack.” The woman responded, “I’m Natalie, Jack’s wife. And you are?”

Allie gripped her chest as if to show the physical heartbreak she was experiencing in that moment before leaning over and throwing up on Andi’s shoes. The screen then faded to black and the credits rolled.

Looking back and Jack and Allie’s trajectory from season 1, Cavanagh told Us, “Jack’s hesitant for a very good reason that isn’t divulged right away, but if you [watch the] campfire scene [where Jack and Alli nearly kiss while drinking wine], you’re wondering, ‘Well, why are they just, you know, going forth?’”

He continued, “Now you realize, ‘Oh!’ And that it’s an adult reason for the way that it got played. As opposed to just dragging the viewer along.”

Cavanagh admitted that the wife twist — or perhaps Natalie is his ex-wife and a potential divorce is not finalized — comes at just the right time to leave fans looking for answers.

“There’s real impetus, and then you kind of drop that bomb at the end, like, “Hi, I’m the wife,’ you’re like, ‘Wait, what?’” Cavanagh said of the shocking cliffhanger. “It’s again well done on the writer’s part.”

Shields, meanwhile, exclusively told Us that she was just as surprised by Jack’s secret wife, confessing, “We have no idea what situation that is.”

Williamson, 27, teased, “No we don’t. Not yet.”

As the show gears up for season 2, Shields, 61, added, “We have an idea of what might be happening. But we just are [unsure].”

She revealed, “But I love to play a character that has this just catharsis, and this, like, ‘Oh, it’s all going to be [good when she] comes forward and then [she’s] slapped on her face.’”

The romance hitch, however, isn’t the only question left unanswered during the season 1 finale.

The majority of the episode centered around Andi’s hunt for her mother, who disappeared 15 years prior. After Andi and Allie’s car broke down on their road trip to New York, park ranger Melissa Grant (Natalie Brown) showed up at the right moment and offered to drive them.

Jack, however, soon discovered that Melissa was not a park ranger, instead she was a hitwoman searching for Andi’s mom.

After Andi and Allie found the exact location of her missing mom, Melissa rushed off ahead of them, getting to the house first. When Andi and Allie arrived, they heard a gunshot before running in to find Jack and other police with a wounded Melissa in custody and Andi’s mom nowhere to be found.

There was, however, a hard drive with Andi’s name on it with a video message from her mother. In the video, Andi’s mom revealed she knew things about some “dangerous” people she worked for and made a deal to keep it secret to protect Andi and her father.

Now that one of the bad guys is getting a retrial, Andi’s mom is considered a loose end so she had to run once again — and she pleaded with her daughter not to try and find her.

“You know [with] that arc something even more monstrous is maybe out there that you don’t see at all,” Cavanagh teased to Us of the threads that will continue to be pulled next season.

The actor explained that there were “such high stakes” throughout the finale, but it was presented as “a melodramatic plot point for Andi” without any indication of the deeper mystery.

“There’s a giant through line that is in every episode, and you don’t even necessarily know that it’s in every episode,” Cavanagh said. “And then the culmination of that is like, ‘All right, no, we all have to be as serious as we can and save somebody’s life or people’s lives here, right?’”

You’re Killing Me was renewed in May for season 2. Season 1 is currently streaming on Acorn TV.
