It looks like North Dakota will get at least 'some' mention in Season 13 of FXX's original comedy series 'It's Always Sunny in Philadelphia.' ***SPOILERS AHEAD***

As we've previously speculated, North Dakota will have some sort of role to play in the upcoming season thanks to the potential storyline surrounding the return of Dennis (Glenn Howerton) to the show. Dennis left at the end of Season 12 to father a child he had with a woman in the Peace Garden State.

Since then, the show has been on hiatus and Howerton's return to the show has been in question, mainly due to the fact that his comedy, 'A.P. Bio' was picked up by NBC. FX has recently released a synopsis for the upcoming season:

The Gang Returns… mostly…. in the 13th season of the FXX original comedy series It’s Always Sunny In Philadelphia. Mac (Rob McElhenney), Charlie (Charlie Day), Dee (Kaitlin Olson) and Frank (Danny DeVito) return to their duplicitous, scheming ways at Paddy’s Pub, while Dennis (Glenn Howerton) takes on the new role of father in North Dakota. Last season, the Gang experienced new highs – Mac acknowledged his sexuality and Charlie convinced The Waitress, his longtime target of affection, to move in with him – and the lowest of lows – Frank became the official beverage sponsor of a terrorist group, Dee helped a man reach rock bottom, and Dennis was investigated for murder. Even without Dennis Reynolds, the Gang has its hands full as Charlie hopes to have a child with The Waitress, Mac sets out to understand his newfound sexuality, Dee takes feminism to new heights, and Frank goes to great lengths for the Gang to experience the greatest moment in Philadelphia sports history – an Eagles Super Bowl victory.

The synopsis seems to lead to the idea that we may see some of Dennis and his adventures in North Dakota, but to what extent exactly? Back in April, Kaitlin Olson mentioned Glenn Howerton's return and said in an interview with The Wrap, “I don’t know the specifics, but I do know how he’s being introduced back in, and it is absolutely hilarious.”

No matter how Dennis comes back on the show, whether he'll be making guest appearances or as part of the main cast, North Dakota is certain to get 'some' mention throughout Season 13 of 'It's Always Sunny in Philadelphia.' The new season begins on FXX on Wednesday, September 5th.
