Spoilers ahead for the fifth episode of Agents of S.H.I.E.L.D. Season 7, called “A Trout in the Milk.“
Agents of S.H.I.E.L.D. has officially gone from making ripples in the time stream to making some pretty big waves, and that’s a big deal for a show set in the Marvel Cinematic Universe. While S.H.I.E.L.D. hasn’t actually had close ties to the larger MCU for years now, and soundly avoided dealing with Thanos‘ snap and the events of Avengers: Endgame, “A Trout in the Milk” did something huge that may have revealed S.H.I.E.L.D.‘s MCU endgame. After the latest developments in the 1970s, the good guys pretty much have to win, even if that doesn’t necessarily mean a happy ending.
