The promo clip from ABC teased "Revenge" season 4, episode 6 spoilers as it shows Emily and Nolan try to wrack their heads together to uncover David's motives.

In the video, Nolan lists down the findings of the FBI on David Clarke as the bureau assessed that he has complex PTSD, psychological fragmentation as well as a loss of safety and trust.

But the "Revenge" season 4, episode 6 video shows that Emily VanCamp's Miss Thorne is not satisfied as she asks Nolan what else the evaluation report said. That gets Nolan wondering what exactly she's looking for.

"It's a gut instinct Nolan. I can't explain it," she says. To which Nolan quips that maybe David will reveal his secrets in the TV interview that night.

To which she replies: " If he's hiding something from the FBI, he's not gonna announce it to the whole world on live television."

"Ems, I respect your instinct," he says. "But I think you're looking for an easier answer because the truth is anything but. It's hard to accept that it happened to someone we love, but it did."

In the "Revenge" season 4, episode 6 spoilers, Nolan and David will headline the panel for a live TV interview in "Damage."

The promo video shows Nolan trying to put Victoria on edge as he threatens her about the truth coming out in the supposed tell-all interview. "Oh, I just love live TV. You never know what's going to happen," he tells her.

But Victoria is not about to go down without pulling her trump card, the fact that David still cares about her. "No matter what happens I will always be on your side," Victoria whispers to Emily's father.
