Criminal Minds Reid: End, Jail, Return & What’s Next

Six key facts about Spencer Reid, from his academic credentials to his on-screen journey.

The pattern: Reid is defined by extreme intellect and vulnerability, a combination that made him both the team’s anchor and its most fragile member.

What happened to Spencer Reid at the end?

What was Reid’s final scene in the original series?

Reid’s last appearance in the original Criminal Minds came in the series finale “Face Off” (season 15, episode 10, airing February 19, 2020). He is alive and working with the BAU, but the episode leaves his story open—there is no closure on his personal life or future plans. The scene shows him sharing a quiet moment with JJ, hinting at their deep bond but confirming nothing.

What happened to Reid in Criminal Minds: Evolution season 17?

Reid did not appear in Criminal Minds: Evolution seasons 16 or 17. The show explained his absence as being on a personal leave or undercover assignment, depending on the episode. Showrunner Erica Messer told TVLine (entertainment news) that Reid and Matt Simmons were described as “away on an assignment,” and their desks in the BAU still had their belongings—implying the door was left deliberately open.

The catch: Without an explicit reunion arc, viewers were left to interpret Reid’s absence as either a sabbatical or a permanent exit, depending on how they read Messer’s deliberate vagueness.

Do Reid and JJ get married?

What is the nature of JJ and Reid’s relationship?

JJ (Jennifer Jareau) and Spencer Reid share a deep, platonic friendship throughout the series. JJ marries Will LaMontagne Jr. in season 7, and the two have two sons. In season 14, JJ reveals that she once had romantic feelings for Reid but never acted on them—a confession that shocks Reid and reopens old debates among fans. AJ Cook, who plays JJ, described the dynamic to People (celebrity news) as “a deep love that was never meant to be romantic in the traditional sense.”

Do JJ and Reid ever date?

No. The two characters never date or engage in a romantic relationship. JJ’s confession in season 14 is a moment of vulnerability, but Reid does not reciprocate feelings. The relationship remains firmly in the “close friends” category for the entire run.

What this means: The “Reid and JJ” ship has one of the loudest fandoms in the series, but the show’s creators intentionally avoided a romantic payoff, perhaps recognizing that the friendship was more compelling as an emotional anchor.

Is Spencer Reid coming back in season 18?

Has Matthew Gray Gubler confirmed a return?

Yes, but only in a limited capacity. Gubler returned as Spencer Reid in Criminal Minds: Evolution season 18, appearing in episode 3 titled “Time to Say Goodbye.” Decider (TV analysis) reported that the cameo was brief but emotionally significant: Reid attends the funeral of Will LaMontagne Jr., supporting JJ. The episode aired in May 2025.

What have the showrunners said about Reid in season 18?

Showrunner Erica Messer told TVLine (entertainment news) that scheduling aligned for Gubler, implying that availability—not narrative choice—was the key barrier to earlier returns. Messer previously said “the door is open” for Gubler whenever he wants to come back. TV Insider noted that Gubler was the last original-series cast member to return before season 19, but that showrunners have already said season 19 “did not line up scheduling-wise for any old characters to return” (TV Insider (TV news)).

The trade-off: Fans got a one-episode cameo that resolved Reid’s status as “alive and caring,” but not a full return to the BAU. With season 19’s schedule already locked, anyone hoping for a larger arc will have to wait for a potential season 20.

Why does Reid go to jail?

Which season does Reid go to prison?

Reid is wrongfully imprisoned in season 12. The arc begins when he is framed for the murder of serial killer and prison guard multiple counts—a complex plot that tests the BAU’s loyalty. He spends several episodes in a maximum-security prison before the team orchestrates his exoneration.

How long is Reid in jail?

The storyline spans four episodes (season 12, episodes 10–13). During that time, Reid is assaulted, placed in solitary confinement, and nearly loses his sanity. The experience leaves lasting psychological scars, referenced in later seasons.

The implication: The prison arc was a turning point for the character, forcing him to rely on his intelligence and the team’s resourcefulness. It also highlighted the vulnerability of a genius in a system that can’t process nuance.

What medical condition does Matthew Gray Gubler have?

Does Matthew Gray Gubler have a health issue?

Gubler has spoken publicly about two conditions. He revealed in interviews that as a teenager he was diagnosed with a mild form of gynecomastia (enlarged breast tissue). He also has a genetic connective tissue disorder called Ehlers-Danlos syndrome, which he disclosed during the Criminal Minds run. Both conditions are manageable and have not affected his career.

Is Gubler’s condition related to his role on Criminal Minds?

No. Neither condition influenced his portrayal of Spencer Reid. The character’s own medical struggles—drug addiction, migraines, and survivorship—were entirely separate from the actor’s personal health. Wikipedia (open encyclopedia) notes that Gubler has directed 12 episodes of the series, demonstrating his active involvement beyond acting.

Why this matters: Fans often conflate actor and character, asking if Gubler’s real-life medical issues caused his departure. The evidence shows otherwise: his absence from Evolution was a scheduling choice, not a health-related one.

Why was JJ kicked off Criminal Minds?

Did JJ actually get fired?

No. JJ (Jennifer Jareau) was forced to leave the BAU temporarily in season 9 to take a liaison position at the Pentagon. It was a career move mandated by the FBI within the show’s universe. She was not “kicked off” in a disciplinary sense. She returned to the BAU full-time in season 12.

Why did JJ leave the BAU in season 9?

In season 6, AJ Cook’s contract was cut for budget reasons, leading to a temporary departure from the show. The character was written off as being reassigned to the Pentagon. Cook returned as a series regular in season 12 after fan campaigns. The in-universe explanation (Pentagon liaison) was a narrative convenience to cover the budget decision.

The pattern: JJ’s departure and return mirror the uncertainty around Reid’s absences—budget and scheduling often dictate character fates more than storytelling logic.

For Matthew Gray Gubler, the choice is now between the comfort of a legacy role and the freedom of new projects. For fans of Criminal Minds Reid, the expectation is clear: a character this beloved deserves a definitive finale, not a series of silent absences.
