Sign in to your ScreenRant account FX's It's Always Sunny in Philadelphia season 18 reveals a major twist of fate for a returning character in its first trailer. Ahead of its premiere on August 17, It's Always Sunny in Philadelphia has now unveiled a new trailer for season 18, teasing some shocking twists and more depravity for the gang in the upcoming episodes. Shockingly, the trailer ends by revealing the death of Carol Kane's Samantha, who became engaged to Danny DeVito's Frank Reynolds after he starred as the Golden Bachelor in It's Always Sunny season 17's ending. Check out the trailer below: The new footage highlights scenes of Kaitlin Olson's Dee Reynolds introducing her future mother-in-law to some eccentric It's Always Sunny in Philadelphia characters on Samantha and Frank's intended wedding day. Among the figures who meet Samantha before the wedding are Gail the Snail, The Waitress, Artemis, and Uncle Jack. However, by the end of the trailer, Glenn Howerton's Dennis Reynolds makes a joke about not wanting the wedding to "come off as some kind of funeral" before cutting to Charlie Day's Charlie Kelly singing "she's dead" as Samantha's corpse is walked down the aisle Weekend at Bernie's style. While it's somewhat surprising that her death was spoiled in the trailer, the questions still remain about how Carol Kane's It's Always Sunny character dies and why Frank still has a wedding ceremony with her body.
