Denis O’Hare is ready to tell Jessie and William’s love story on This Is Us.

The actor joined the NBC hit midway through its first season, playing Randall’s biological father, William’s, longtime partner, Jessie. Fans last saw Jessie in the season’s penultimate episode, which featured a memorial service for William. He, of course, died in the episode prior, while on a trip to Memphis with Randall.

“You know, I think we all knew it was coming,” O’Hare tells ET. “I thought it was an amazing moment to explore a rich heritage for Randall and for William. I thought it was great that Randall sort of, I don't know, imagine what his life would've been like if he had had that dad.”

Now, O’Hare hopes season two will explore Jessie and William’s life together, even though William is gone.

“I think we're going to find out more about their past,” he teases. “I hope. I mean, come on. The show exists in so many time periods, nobody's ever really dead. It's kind of like this show, I'm in good company.”

ET caught up with O’Hare at PaleyFest in Los Angeles, where he was celebrating his other hit show, American Horror Story: Roanoke. For more from that panel, check out the video below.
