Ryan Eggold left The Blacklist when his character, Tom Keen, was killed off in Season 5’s fall finale.
Before being killed off, Eggold led The Blacklist’s short-lived spinoff series The Blacklist: Redemption, which answered a lot of questions surrounding the origin story of the character.
The show’s investment in Tom Keen made his being killed off all the more shocking, and, in the end, puzzling.
When the series was not renewed, he returned to The Blacklist.
