Famke Janssen will play Susan Hurst, nicknamed "Scotty". Although it is not known what role this character will play in the spin-off, it is reported that her influence on Tom (played by Ryan Eggold) in the play is similar to the influence of "Red Devil" Reddington (played by James Spader) on Liz (played by Megan Boone), but the specific relationship between the two is still unknown. This character will appear a week in advance in episode 21. The spin-off will be created by Berkenkamp and Eisendra, who will serve as executive producers of the show together with John Davis and John Fox of "The Blacklist".
