After a year of speculation, it has been confirmed: Glenn Howerton is officially in Season 13 of It's Always Sunny in Philadelphia. Howerton's Dennis Reynolds character left Paddy's Pub at the end of Season 12 to go be a dad in North Dakota and in real-life, Howerton went on to star in A.P. Bio with comedian Patton Oswalt. It's Always Sunny fans were worried that Howerton was done with the show as the rest of the cast wouldn't confirm nor deny that he had left for good.
It's Always Sunny in Philadelphia star and creator Rob McElhenney confirmed that Glenn Howerton is back for the new season, stating, "He's pretty much in every episode." McElhenney and Charlie Day spoke to reporters at the FX presentation at the Television Critics Association summer press tour today to reveal the news. When it comes to how many episodes Day said, "He's in the majority of them." Before the cast knew that he was officially coming back, they came up with some cool limited-roles that fortunately won't have to be explored in Season 13.
Mac (Rob McElhenney), Charlie (Charlie Day), Dee (Kaitlin Olson) and Frank (Danny DeVito) were all featured in some promotional material for the upcoming season, with a possible hint of Glenn Howerton in the background. The Friday the 13th-inspired art featured the gang running away from a cabin with a character that looked very much like Jason Voorhees, who many fans believed to be Howerton. Whatever the case may be, it doesn't matter now that it's official that Howerton is back with the gang to continue delivering the cult comedy.
When asked about one of the possible ideas that was considered around the possibility of Glenn Howerton's reduced role, Charlie Day says that they thought about an "all-female" reboot of the iconic Season 10 episode The Gang Beats Boggs, which would have had Dee, The Waitress, Artemis, Mac's mom, and Charlie's mom on a flight to the Los Angeles Women's March. During the march, the women would attempt to beat Wade Boggs' legendary drinking record. Hopefully it's not too late for that episode to happen, because that sounds like a pretty awesome idea.
Season 13 of It's Always Sunny in Philadelphia will premiere on FXX Wednesday, September 5th and will have a whole bunch of topics to deal with. Dennis' fatherhood is one of the major ones, but Mac's sexuality will also have to be further explored to help him understand it. Dee will be taking feminism to new heights, and Frank is going to great lengths for the gang to experience the greatest moment in Philadelphia sports history, which is an Eagles Super Bowl victory. Overall, Season 13 of It's Always Sunny in Philadelphia sounds like it's going to be perfectly bonkers, which is exactly why fans keep coming back to the cult favorite comedy.
