That’s the position Glenn Howerton left fans in after Dennis Reynolds’ season 12 exit, with his NBC comedy A.P. Bio fueling rumors that he was done with the show he co-created with Rob McElhenney and Charlie Day (Yahoo News / Entertainment Weekly) — and here’s what actually happened, which rumors never held up, and why the question keeps coming back.

Glenn Howerton at a glance
Five details carry most of the search traffic, and one pattern shows up fast: the rumors have always outrun the documentation.
| Detail | Information |
|---|---|
| Born | April 13, 1976 |
| Birthplace | Okinawa, Japan |
| Occupation | Actor, writer, producer |
| Known for | Dennis Reynolds on It’s Always Sunny in Philadelphia — a role he has played since the first episode in 2005 (The Independent) |
| Co-creator of | It’s Always Sunny in Philadelphia, with Rob McElhenney and Charlie Day (Yahoo News / Entertainment Weekly) |
| Other headlining role | A.P. Bio (NBC), which fueled exit speculation (The Daily Beast) |
| Season 13 | Returned as an actor after Dennis’s season 12 exit (The Independent) |
| Status on the show | Never officially left; said so publicly in 2017 (Bleeding Cool) |
The catch: the more the record is laid out, the smaller the ‘exit’ story gets — a reduced season, a side project, and a character who chose fatherhood.
Why did Glenn Howerton leave Always Sunny season 13?
Dennis Reynolds did not quietly disappear. In the season 12 finale, he tells the rest of the Gang that he cannot continue the same lifestyle — he has discovered he fathered a child in North Dakota, and he wants to become a father (The Daily Beast (news and culture); TheWrap). The moment was written as a character turn, but it collided with a real-world schedule story: Howerton’s separate NBC comedy A.P. Bio was on the air, and the combination fueled public speculation that he was done for good.
Dennis’s exit was a storyline choice before it became a scheduling story: a character deciding to be a father, not an actor handing in notice. That order of events is why the cliffhanger felt like a resignation.
Did Glenn Howerton try to leave Sunny?
- Howerton has said he considered quitting because he feared the series had peaked or might wear out its welcome (The Independent (UK news)).
- He also wanted to pursue other career opportunities and felt boxed in by the show (The Independent).
- The doubts predate season 13: Howerton has said that during season 6 he did not want to continue because other career goals were being obstructed (SlashFilm (film and TV news)).
- CBR reported that Rob McElhenney believed the desire to leave would pass and kept writing Dennis into the series (CBR (pop-culture outlet)).
The pattern: ‘leaving Sunny’ was never one clean decision. It was burnout, ambition and a side project colliding — with a character arc that happened to look like a resignation letter.
Why is Dennis barely in season 13?
- A.P. Bio’s production overlapped with Sunny’s season 13, and that overlap became the default headline explanation (The Daily Beast).
- Howerton pushed back on that reading, telling CBR the ‘he left for A.P. Bio’ story was a misconception (CBR).
- In his own telling, Dennis’s absence was an artistic decision rather than merely a logistical consequence (TheWrap).
The takeaway: the reduced role was part story, part schedule — and neither part added up to a permanent exit.
Did Dennis quit Always Sunny?
- On screen, yes: Dennis chooses fatherhood over the Gang in the season 12 finale (TheWrap).
- Off screen, no: Howerton said in 2017 that he had not officially left the show, while adding that Dennis could be gone for good (Bleeding Cool (pop-culture news)).
- By season 13, he was back as an actor — the absence was an arc, not an exit (The Independent).
What this means: the character did the quitting, and the actor never did. The writing even left the door open by framing Dennis’s departure as ‘maybe,’ not ‘forever.’
The record keeps pointing the same way: the character left, the actor stayed.
Who created Always Sunny?
The show’s origin is not in dispute, which makes it a useful anchor when the exit rumors get loud.
- It’s Always Sunny in Philadelphia was created by Rob McElhenney, Charlie Day and Glenn Howerton (Yahoo News / Entertainment Weekly).
- Howerton has been associated with the series since its first episode in 2005, playing Dennis Reynolds throughout (The Independent (UK news)).
- His character is part of the show’s dysfunctional core: self-absorbed, manipulative and potentially sociopathic by design (TheWrap (entertainment trade press)).
The actor who reportedly nearly quit is also one of the three people who created the show — which is why the ‘he’s gone’ story never fully added up.
Why this matters: a co-creator walking away would be a much bigger story than an actor reducing his hours, and the record shows neither happened.
What ethnicity is Glenn Howerton?
Glenn Howerton was born on April 13, 1976, in Okinawa, Japan, to American parents. The birthplace raises the question often, but the public record identifies him as an American actor — the same record that places him in U.S. television since 2005 (The Independent).
The pattern: a birthplace can look like an ethnicity even when it isn’t one. Okinawa explains where Howerton entered the world; it does not define his nationality.
Was Glenn Howerton’s wife in Always Sunny?
The short answer is yes, with a qualifier about the size of the role.
- Howerton is married to Jill Latiano.
- Latiano appeared in a cameo role on It’s Always Sunny in Philadelphia.
The catch: a cameo is easy to misremember as a recurring part, which is exactly how this question keeps resurfacing.
What is Glenn Howerton’s illness?
Dennis Reynolds is a fictional character written as self-absorbed, manipulative and potentially sociopathic. There is no public record suggesting Glenn Howerton shares his TV counterpart’s diagnosis — or has any serious illness.
The illness rumor appears to grow out of Dennis’s on-screen behavior: the series depicts him as self-absorbed, manipulative and potentially sociopathic (TheWrap (entertainment trade press)). That is a character note, not a medical record. No confirmed report or public statement supports claims that Howerton himself is seriously ill.
Why this matters: the line between actor and role is exactly where this rumor started, and exactly where it falls apart.
Key dates in the Always Sunny exit story
The story has several clear beats, and the pattern is consistent: every ‘exit’ was followed by a return.
- — Born in Okinawa, Japan.
- — It’s Always Sunny in Philadelphia premieres; Howerton co-creates the series and plays Dennis Reynolds (Yahoo News / Entertainment Weekly).
- — Howerton has said he burned out and did not want to continue (SlashFilm (film and TV news)).
- — Howerton says he has not officially left, while leaving Dennis’s future open (Bleeding Cool (pop-culture news)).
- — Dennis leaves the Gang to become a father (The Daily Beast).
- — Season 13 airs with a reduced Dennis; Howerton returns as an actor (The Independent).
The signal: every reported break came with a counter-move — a public statement, a writing decision, or a return to the screen.
Confirmed facts vs. what’s unclear
One list settles the record; the other explains why the rumors survived.
Confirmed facts
- Howerton plays Dennis Reynolds and has been tied to the series since 2005 (The Independent).
- He co-created the show with Rob McElhenney and Charlie Day (Yahoo News / Entertainment Weekly).
- Dennis’s season 12 exit was written as a choice to become a father (TheWrap).
- Howerton returned as an actor in season 13 (The Independent).
- According to Bleeding Cool, Howerton said in 2017 that he had not officially left the show (Bleeding Cool).
What’s unclear
- Whether the 2017 ‘we’ll see’ meant a real exit was ever on the table (Bleeding Cool).
- Whether A.P. Bio was the true driver of the reduced role — Howerton calls that a misconception (CBR).
- Whether he was fully absent from the writers’ room in seasons 13–14, as reports claim (CBR).
- Whether illness rumors have any basis — no confirmed public report supports them.
- The exact scope of Jill Latiano’s appearance — remembered by some fans as bigger than the cameo it’s described as.
What this means: the unresolved items are about emphasis, not existence. Howerton stepped back, returned, and never issued the resignation that fans imagined.
What Howerton said about leaving
The record is full of secondhand summaries, but the direct statements cut through the noise.
“It’s time for that character to change.”
— Glenn Howerton, on Dennis’s future, as told to The Daily Beast
In 2017, Howerton said he had not officially left It’s Always Sunny.
— As reported by Bleeding Cool
Rob McElhenney reportedly believed Howerton’s desire to leave would pass, and continued writing Dennis into the series.
— Reporting by CBR
The trade-off: Howerton got his artistic answer — Dennis’s story changed — and the show kept its co-creator. Both sides of the ‘departure’ got exactly what they needed.
So did Glenn Howerton actually leave?
The short answer is no. Howerton reduced his presence in season 13, returned as an actor, and let Dennis Reynolds carry the exit storyline instead of announcing one of his own. For fans still hunting for a clean ‘he quit’ headline, the implication is clear: keep watching the Gang, because the co-creator and his character never really left — or keep waiting for an exit that already came and went.
