Agents of S.H.I.E.L.D. will return on ABC sooner than previously expected. In a Valentine's Day-themed promo, Marvel revealed Season 6 will air in May.

The latest promo explores several different relationships on the series, from newlyweds Leo Fitz and Jemma Simmons to Alphonso "Mack" Mackenzie and Elena "Yo-Yo" Rodriguez to Phil Coulson and Melinda May. The brief video is capped off with a title card that shows the S.H.I.E.L.D. logo and a "Happy Valentine's Day" message. Just below the series' logo, it announces May 2019 as the release month.

Previously, Agents of S.H.I.E.L.D. Season 6 was expected to air this summer, with some reports setting it in July. This promo is the closest we've come to an official release date, though the day has not yet been announced.

Notably, this means the series will return after the Marvel Cinematic Universe-shaking events of Avengers: Endgame, which hits theaters on April 26. As such, S.H.I.E.L.D. will bypass the events of Infinity War entirely, considering that Season 5 concluded just after that film and Season 6 picks up after Endgame.

As revealed earlier today, Season 6 will take place a year after the events of the Season 5 finale. Coulson actor Clark Gregg previously revealed the season will be broken down into two storylines: the first half will explore "strange anomalies," while the second half will send the team into space to find Fitz.

Agents of S.H.I.E.L.D. is set to return for its sixth season in May 2019 on ABC with 13 new episodes. The series stars Ming-Na Wen, Chloe Bennet, Henry Simmons, Iain De Caestecker, Natalia Cordova-Buckley and Elizabeth Henstridge.
