"The Last Death of Henry Morgan", the 22nd and final episode of the American television series Forever, first premiered in the United States on May 5, 2015 on ABC.

While New York Police (NYPD) detectives Jo Martinez (Alana de la Garza) and Mike Hanson (Donnie Keshawarz) and Assistant New York City medical examiner Lucas Wahl (Joel David Moore) examine the body of a female murder victim, a museum curator who discovered a dagger, New York City medical examiner Dr. Henry Morgan (Ioan Gruffudd) and his son Abe (Judd Hirsch) hold a private funeral for the family matriarch Abigail.

Henry tells Abe that he plans to seek revenge against Adam (Burn Gorman), an immortal who played a role in Abigail's death.

Henry and Jo learn from the curator's boss and Aubrey Griffin (John Noble), a specialist in Roman era antiquities, that the discovered dagger was used in the assassination of Julius Caesar.

After Lucas' revelation that both victims' attacker wore nitrile gloves, Henry and Jo return to the museum.

Adam forces Henry to turn around by firing the flintlock into the air and producing a photograph of the Morgan family from 1945.

Later, Jo arrives at the antiques shop with Henry's watch and the family photograph that Adam left at the scene.

Henry claims that a sniper shot him in the chest earlier in World War II; Abigail is reluctant to discuss the cigarette burn that her ex-boyfriend left on her neck.

Instead, they researched possible alternatives and decided that an air embolism to the brainstem which would paralyze Adam but keep him aware of his surroundings would serve as the best method of revenge.

[4] At the beginning of the series, Miller and the writers decided that the concept of people learning Henry's secret would serve as a series-long story arc.

[8] The character of Henry's stalker Adam, portrayed by Burn Gorman, made his fifth physical appearance in the series during the episode.

[13] The writers created a plot twist by introducing Adam as Henry's assigned therapist;[2] Gorman used his British accent in the episode.

[7] In spite of the twist, viewers, such as TVLine's Kimberly Roots, immediately, and correctly, guessed that Gorman was Adam.

In addition, "The Last Death of Henry Morgan" matched Forever's own best ratings from December 2, 2014, in adult viewers 18-49.

When "The Last Death of Henry Morgan" aired on June 16, 2015, in France, it and the previous episode averaged 6.1 million viewers, or 26.3% of the audience.

In his "Critic's Corner" column, Robert Bianco of USA Today felt that the mention of Julius Caesar's assassination was unbelievable but liked the episode's ending and Noble's performance.

[23] Although Den of Geek's Billy Grifter found the condition of the dagger and the firing of the pistol unbelievable, he gave the rest of the episode a positive review, stating, "As conclusions go, Forever's finale wasn’t half bad, even though they really only gave themselves 42 minutes to wrap up lots of plot threads.

[25] Although they thought that the scene where the victim's friend was dying was disgusting and that Henry giving Adam the air embolism was cruel, Kate Aquillano, Marielou Mandle, and Pegah Rad of AfterBuzz TV generally liked the episode.
