The second season of Kaitlin Olson’s Fox sitcom “The Mick” ended last night, so now it’s time for her fans to look forward to more “It’s Always Sunny in Philadelphia.” But should Glenn Howerton groupies do the same?

We just asked Olson, who stars on the cable comedy and is married to showrunner and co-star Rob McElhenney, for the latest on Howerton’s/Dennis’ FXX future.

“I do know that Glenn Howerton is coming back for some episodes,” Olson told TheWrap. “I don’t know the specifics, but I do know how he’s being introduced back in, and it is absolutely hilarious.”

The rest of her response was too cagey to even publish, as Olson tip-toed around sharing any spoilers. Still, that’s good to know.

Howerton has played just as coy about his own future on “Sunny.” Earlier this year, the “A.P. Bio” star said that it is “possible” his character Dennis will be back on “Always Sunny.”

“Telling you whether or not Dennis is coming back would be giving away the plot of the next season,” Howerton wrote on Twitter. “So… to clarify once and for all. I don’t know if Dennis is coming back. He left the bar. We take that plot choice seriously.”

For his part, Howerton maintains that he’s not going anywhere.

“I don’t know why the narrative continues to be centered around whether ‘I’m’ coming back. I’m here,” he continued. “It’s whether or not ‘Dennis’ is coming back. Dennis could be gone forever.”

At this point, TheWrap has had multiple conversations with both Olson and Howerton about what’s next for Dennis. Don’t hold us to it or call us crazy, but we cannot rule out that all of this noncommittal talk is going to result in some sort of an “evil twin” storyline.

Season 13 of “It’s Always Sunny in Philadelphia” is expected to premiere next year. Though Olson’s “The Mick” Season 2 is over, readers can catch Howerton tonight on NBC’s “A.P. Bio,” which airs at 8:30/7:30c.
