Here's some scoop on The Blacklist from Entertainment Weekly's Natalie Abrams' The Spoiler Room column, which was posted on 3/3/17.
How did Red have so much info on Tom on The Blacklist? Is he connected to Christopher Hargrave’s disappearance? — Kyle
Just because Red knew Tom was Scottie’s son does not mean he played a role in the abduction. In fact, the writers are trying to keep the mythos of each show somewhat separate. “What Reddington told Tom was to stay away from it,” EP Jon Bokenkamp says. “There’s no good that is going to come from [him] going into this world and asking these questions. Red is not somebody who has a tremendous amount of love for Tom. They’ve had their own fraught relationship, but that did seem genuine. That was one of the most caring things Reddington’s ever told Tom, and he probably said that because he cares about Elizabeth and Agnes. But as far as the history, the two shows share some DNA, because they live in the same landscape, and there’s great potential for some crossovers, but I don’t think Red had anything to do with the origin of this story. Of course, he’s always full of secrets, so who knows? But it feels like it stands on its own.”
