Tom Keen, Liz's elusive and untrustworthy husband, has only been making appearances and never sticks around much. Previous episodes have seen glimpses and flashes of him, but in episode 16, whose title is Liz's husband's name, viewers will finally see a lot more of Tom Keen.

Evidence against Liz is building up on the harbormaster case and the only way to save her is to find Tom and make him confess. Red and Ressler kick their search into high gear in a desperate attempt to save Liz. Red has a lead that lands them in Dresden, Germany where Tom has been hanging out with a group of undercover skinheads, reports International Business Times. The duo come face-to-face with Tom but will have to battle with his newest friends in order to get him out of Germany alive. Will Tom take the fall for Liz? It seems he will, if promotional clips and sneak peek videos are an indication of what's to come.

But how will Liz handle Tom's re-appearance? And will the agent forgive him as a result of this grand gesture? Probably not, as actress Meghan Boone gives some insight into her character's mind. Boone told TVGuide, "She thinks of him as a very dangerous person now. Anytime he comes into her life from this point on is going to be an extraordinary circumstance -- whether he comes into her life seeking redemption...or if he comes into her life to try and harm her again and try to manipulate her. She's going to be very skeptical." Looks like Liz isn't going to trust him anytime soon after realizing her marriage was a sham.

With Tom's return, action sequences in Germany and Liz finally getting cleared in the harbormaster's murder, tune in to "The Blacklist" on Thursday, March 19 at 9 p.m. on NBC.
