Red (James Spader) is getting a blast from his past when The Blacklist resumes its seventh season later this month.

Joely Richardson will guest star in the second hour of the back-to-back episodes on Friday, March 20, and NBC has released photos showing that her and Spader's characters will be getting close.

Richardson's Cassandra Bianchi turns to her ex for help while after a big score, and the criminal "has a deep history with Red," executive producer John Eisendrath revealed for TVLine. Creator Jon Bokenkamp added that the episode, "Cornelius Ruck," is "a fun, incredibly intense whodunit."
