The Blacklist is an American crime-drama TV series. It premiered on NBC on September 23, 2013. It ran for ten seasons and ended in July 2023 with 218 episodes.
The show follows Raymond “Red” Reddington. He is a smart and charming criminal mastermind. He suddenly turns himself in to the FBI. He offers to help them catch other dangerous criminals. But he has one rule. He will only work with a new profiler named Elizabeth Keen.
The show started as a “criminal of the week” story. But over time, it grew bigger. It added big conspiracies, secret identities, and many personal betrayals. It became a huge and complex mystery.
FBI Special Agent Donald Ressler is one of the early main characters. He is played by Diego Klattenhoff. Ressler begins as a strict, rule-following agent. He wants to arrest Reddington. He only trusts the law and proper procedure.
Over the ten seasons of The Blacklist, Ressler goes through a lot. He faces difficult moral choices, suffers personal loss, and forms new alliances. He deals with fear, guilt, and trauma. Because of this long journey, many fans wonder what happens to him in the end. The question of his fate remains a major topic for viewers.
What happens to Ressler in The Blacklist?

When The Blacklist begins, Donald Ressler is a classic FBI agent. He follows rules. He trusts the law. He likes order and discipline. He does things “by the book.”
Ressler has chased dangerous criminals for years. He does not trust Reddington at first. He prefers real police work, not Red’s flashy style.
Ressler’s whole deal traces back to his dad, who was a Detroit cop. One day, his own partner straight-up murders him. Why? Because the man wouldn’t play dirty or pocket bribes. That kind of blow messed up Ressler’s family big time and lit the fire for him to get into law enforcement in the first place.
Across The Blacklist, Ressler’s story becomes more complicated. His morals change over time. His beliefs get tested again and again. Ressler is obsessed with Reddington at first. He wants to catch Red, as he does not trust him. This obsession hurts his personal life. It even ruins his engagement. For many seasons, this chase shapes his choices.
He also faces many dangerous moments. In the episode Anslo Garrick: Conclusion, he is held at gunpoint. He is forced to work with Reddington to survive. He lives, but the event leaves emotional scars. He also gets hurt in other traps across the series.
Ressler struggles inside, too. He carries stress, grief, and guilt. After several traumatic missions, he starts taking pain pills. This shows how hard the job is on him.
As The Blacklist grows, Ressler slowly changes. He is still strict. He still loves the law. But he becomes less rigid. He learns that working with Red sometimes helps people. He never fully trusts Reddington, but he understands him better.
By the end of The Blacklist, everything has changed. The finale aired in July 2023. Many storylines end. Ressler survives. He continues living after the finale.
In the final chase, the FBI is under pressure to catch Reddington. Congressman Arthur Hudson pushes hard. During a tense moment, Reddington shoots Hudson. Then he shoots Ressler, too. But Red is not trying to kill him. The bullets hit Ressler’s vest. So, he survives.
After this, Reddington escapes to Spain. He walks alone in the countryside near Seville. There, a bull charges him. He is killed instantly. Ressler is the one who finds Red’s body. He looks shocked and tired. He calls Harold Cooper and says he found Reddington.
This moment means a lot. Ressler started as a strict, by-the-book agent. By the finale, he has seen years of violence, lies, and loss. Finding Red’s body shows how far he has come. He is older, wiser, and deeply changed. But he is alive. And The Blacklist ends with him standing over Red, the man who changed his life forever.
The fact that Ressler lives through the final fight is important. Ressler is a survivor. He outlasts the long war with Reddington. He also outlasts the political pressure around the case. His loyalty and strength stay with him until the very end.
Finding Reddington’s body is a heavy moment. It is emotional for Ressler. The Blacklist does not tell us what Ressler does after this. But we know he carries all the weight of the past years. He holds the loss of friends, partners, and even strange allies.
Some fans said the ending felt incomplete. They wished the finale had shown more about each character’s future. Ressler’s future is left open for viewers to interpret. But one thing is clear. Ressler survives. He is hurt but alive. He is the last one standing when Reddington dies. And he is the person who witnesses the real end of Reddington’s story.
