Agents of S.H.I.E.L.D. debuted in 2013 on ABC to bring Clark Gregg's Phil Coulson back to life after his Avengers demise. The first season was more or less beholden to the upcoming release of Captain America: The Winter Soldier in 2014, which revealed Hydra within the ranks of S.H.I.E.L.D. and completely turned the TV show's premise upside down. It also involved a game-changing twist for Brett Dalton's Ward that remains one of the show's most shocking, and the actor opened up about Ward breaking bad nearly ten years later.
For a quick recap: Grant Ward, who previously seemed like the most straight-laced member of Coulson's team, was revealed to be a Hydra double agent in the "Turn, Turn, Turn" episode of Season 1 that aired on April 8, 2014, just days after The Winter Soldier hit theaters with the S.H.I.E.L.D./Hydra reveal. It was a massive game-changer that raised the stakes for the rest of the team, and arguably was the last and biggest tie between S.H.I.E.L.D. and the larger MCU. Dalton would go on to portray Ward throughout the first four seasons.
