 Ultimately , the season featured several tie @-@ in episodes with Marvel Cinematic Universe films : the episode " The Well " takes place directly after the events of Thor : The Dark World ; the episode " T.A.H.I.T.I. " introduces the alien race the Kree to the MCU ( confirmed as such in the second season ) , members of which play a significant role in Guardians of the Galaxy ; and the episodes " End of the Beginning " and " Turn , Turn , Turn " revolve around the events of Captain America : The Winter Soldier . Due to Captain America : The Winter Soldier revealing that Hydra had infiltrated S.H.I.E.L.D. with sleeper agents , the season sees a retooling for the final six episodes . Regarding the synergy the show has with addressing events from the films , Loeb said " It 's an extremely unique experience that doesn 't exist anywhere else out there in the entertainment business " . The characters face the Hydra issue head on , while experiencing trust issues within themselves . Jed Whedon added that the Hydra element , which the show could not mention until after the release of The Winter Soldier in order to avoid spoiling the film , also attempts to address the lack of characters from the comics , a complaint fans had throughout the season , while also tying established threats such as the Clairvoyant , Project Centipede , and Deathlok , back into Hydra .
