ET’s Katie Krause caught up with the actor behind the character, Justin Hartley, at Entertainment Weekly’s 2018 Pre-Emmy Party on Saturday to chat about what fans can expect to see in season three, and if he’s got what it takes to make it through his battle with addiction and grieving the loss of his father Jack (Milo Ventimiglia).

Well he’s fresh from that. He’s in recovery. He’s in remission but he’s barely there. I think he’s got one foot in the door, but the other one’s on a banana peel, maybe.”

Justin added that his on-screen alter ego’s demons concern him, including whether or not he’ll survive and make it through all the ups and downs. On the popular drama, fans have seen his co-star Sterling K. Brown’s character Randall aged in the future, but not Kevin.

” … Because on our show you never know, you might not live,” he acknowledged, before answering “Yes!” when asked if he’s worried about Kevin dying.

“I’m not going to — listen, I’m not too cool for school. I’m going to tell you the truth, I mean, ‘worry’ is a strong word. I don’t worry about it but I do think about it when people bring it up. [Kevin] was on very thin ice there last season so we’ll see what happens.”

Hartley also teased that there will be a This Is Us cast surprise at the Emmys!

“I can tell you that I know what it is. I can tell you that it’s very, very, very cool! Very well-deserved. It’s special, it’s going to be fun, and I think everyone will enjoy it, but I think especially — internally — we’ll enjoy it as a cast. It’s amazing! It’s awesome!”

“I think it’s going to make people stand up and cheer,” he added. “It involves the entire cast because we’re so close.”
