This report contains major spoilers from Marvel’s Agents of S.H.I.E.L.D and Captain America: The Winter Soldier. Read with caution.

Last night’s episode of Agents of S.H.I.E.L.D correlated with the outcome of Captain America: The Winter Soldier. At the end of The Winter Soldier, S.H.I.E.L.D was completely destroyed by the reveal that the company had been infiltrated by a group named Hydra. This meant even some of the most trusted agents could be compromised.

The S.H.I.E.L.D episode managed to tie together the events of Captain America and the series, while keeping one of the movie’s major twists a secret; this twist involved Nick Fury’s (played by Samuel L. Jackson) resurrection. On the show, most of the agents of S.H.I.E.L.D believe Fury is dead, but those who only watch Agents of S.H.I.E.L.D, and have not seen Captain America 2, will also be in on the secret soon.

Jackson told New York Magazine’s Vulture column that he just filmed scenes for the season finale. “I just shot the end-of-the-season show.” However, he remained quiet on any details about his upcoming guest appearance. He even joked that giving away more details could result in his firing. “You’re trying to get me fired and killed! I don’t talk about Marvel’s business. None of us do,” he told the Vulture reporter.

Nick Fury isn’t the only character from the Marvel movie universe to make a guest appearance on ABC’s Agents of S.H.I.E.L.D. Jaimie Alexander reprised her role as Sif from Thor and Thor: The Dark World. Cobie Smulders, who played Maria Hill in The Avengers and Captain America: The Winter Soldier, appeared in the pilot episode of S.H.I.E.L.D.

Smulders will also appear on an upcoming episode of S.H.I.E.L.D, just in time for May sweeps. Fury and Hill both helped take down S.H.I.E.L.D in Captain America: The Winter Soldier, so they may take on a similar role in the series.

Jackson appears on S.H.I.E.L.D’s May 13 season finale, and Smulders appears on the April 29 episode.

Agents of S.H.I.E.L.D airs Tuesday nights on ABC at 8:00 pm EST.
