Justin Hartley is opening up about that shocking cliffhanger from the fall finale of This Is Us.

ET's Lauren Zima caught up with the 40-year-old actor on the red carpet at the GQ Men of the Year event in Los Angeles on Thursday, where he shared his thoughts on SPOILER! Kevin's DWI.

"At that point we were already pretty far into the story, so I kind of knew the nitty gritty parts of where that story was going and how deep it was going to get and sort of how far down they were sending him," Hartley said of his reaction to reading Kevin's unfortunate fate for the first time. "These writers are doing such a good job of telling honest, true stories, even when its hard to watch and uncomfortable sometimes. But it's honest and I think that's the main thing we're trying to do each and every moment, and I think they do a good job of that."

At the end of the episode, we saw a panicked Randall (Sterling K. Brown) and Beth (Susan Kelechi Watson) learning that one of their daughters, Tess (Eris Baker), was in the car when Kevin was pulled over. Hartley teased how Kevin and Randall's relationship will be affected moving forward.

"Well, its not good, right? I mean, that can't be good and Randall is, like, a big dude," he shared. "I'm not sure you want to piss that guy off. But in all seriousness, that's a serious thing. Regardless of what he knew, you can't get into a car when you're inebriated and drive around."

"[Tess] is in the back seat and it just turns into something huge and out of control," he continued. "They have made so many end roads to making the relationship viable when it was kind of broken when we found them, and I hope this doesn't go down the path where its like they have to start over. Maybe because of the repairs they've done recently they were able to find common ground and go from there and sort of understand each other and kind of grow. I think that's an important relationship to have, Kevin and Randall."

Off the show, Hartley appears to be loving life as a married man. He recently tied the knot with his longtime love, Chrishell Stause, in October, and tells ET that having a wife is "fantastic."

"There's something really cool about saying 'wife' to someone that you've known for a really long time," he gushed. "We're having a blast. We're still celebrating, you know? So, hopefully that continues for forever."

He also revealed that the two will be spending the holidays together at home.

"Quiet, simple, easy, open presents," he said. "Do the traditional presents under the tree and Christmas music. We have this really cool record player, and we do the whole thing where we buy LP's and flip them around. Like DJ Christmas day. It's great!"
