Ryan Eggold may have started out “The Blacklist” as the seemingly innocuous husband to FBI agent Elizabeth Keen (Megan Boone), but the seeds of doubt were quickly planted about Tom, for both Lizzie and the audience.

Things are coming to a head this week and next on the NBC drama, with Liz hot on the trail of Jolene’s killer, who she does not know is her husband. Eggold teases for the “Today” hosts that while exciting plotlines are happening, there’s still a long way to go.

“I think the exciting thing about Tom is there’s a lot more to go. There are so many secrets on the show and there’s a lot we’re going to answer at the end of the season, but those answers lead to questions and further avenues to go down,” says Eggold. “What I love about it is you have everything on the surface and you introduce all these characters, but then you go, ‘Wait, he has a secret,’ ‘Oh wait, she’s lying.’ And all these layers we can continue to pull back is what I think is interesting about it.”

He adds that while he had some knowledge of his character’s darker side, he wasn’t completely clued in. “I had some idea that this was going to happen, but of course, I didn’t know the exact way that it was going to go. It’s still sort of taking shape now,” he says.

Eggold then is asked to reveal something they don’t know about him and he says he has on women’s underwear — but we think he’s kidding.

“The Blacklist” airs Monday nights at 10 p.m. ET/PT on NBC.
