The Return of the First Avenger
Sava felt that having the series introduce the race made "Agents of S.H.I.E.L.D." "an essential part of Marvel Studios' bigger plans for the future", explaining that "the series has become more and more connected to the larger MCU since "Captain America: The Winter Soldier", but it's always been in a reactive role. Stuff happens in the movies, and "Agents Of S.H.I.E.L.D." deals with the fallout. Not anymore. This show is making things happen, and these events will clearly impact the future of the MCU because we know there's an "Inhumans" movie planned for 2019." Sava also mentioned that introducing the Inhumans "on a personal level rather than a cosmic level" via the television series makes "the whole idea a bit easier to swallow" for the general MCU audience.
