SPOILER WARNING: This article contains major spoilers for "Self Control," the latest episode of "Agents of S.H.I.E.L.D."


"Agents of S.H.I.E.L.D." took a dramatic turn in its latest episode, "Self Control." The show not only wrapped up its Life Model Decoy double-agent storyline, it set up the plot for the final part of Season 4 -- one that puts Hydra and Grant Ward back at the forefront of the series.

The episode, which was written and directed by showrunner Jed Whedon, put all of the main agents into Doctor Radcliffe's magical framework -- a Matrix'esque world where certain life events can be re-lived without pain. The final moments of the episode showed clips of where each character in the framework fonds themselves. Coulson is teaching in a school, Fitz is living a wealthy life, Simmons is dead, Daisy and Ward (welcome back Brett Dalton!) are living together, and May is working for Hydra.

Wait, Hydra?

The new promo re-shows all those clips, plus it debuts the central logo and subtitle for the season: Agents of Hydra. It seems like when the show resumes in April, the agents will be living in a framework where Hydra triumphed during the events of "Captain America: The Winter Soldier." Apparently, when you cut off one head of Hydra in the real world, it just regrows inside the framework.

Airing Tuesdays at 10 pm ET/PT on ABC, “Marvel’s Agents of S.H.I.E.L.D” stars Clark Gregg as Agent Phil Coulson, Chloe Bennet as Daisy “Quake” Johnson, Ming-Na Wen as Melinda May, Iain De Caestecker as Leo Fitz, Elizabeth Henstridge as Jemma Simmons, Henry Simmons as Alphonso “Mack” Mackenzie and more.
