<P> The episode "T.A.H.I.T.I." introduces the Kree alien race to the MCU, members of which play a significant role in Guardians of the Galaxy . This begins a storyline that recurs throughout the series, and introduces Inhumans to the MCU, with Jed Whedon saying that it was something "in the works" for a long time, as Marvel Studios had plans for an Inhumans film, and this would be "one of the first instances where we get to start planting the seeds on the show before the film ." The third season introduces the concept of the Secret Warriors, with new Inhuman characters inspired by the comic of the same name, while also retconning the history of Hydra in the MCU, tying it into the Inhumans storyline . Gregg noted in January 2016 that the "writer and director (of the Inhumans film) will have free rein to do what they want to do with the Inhumans, but hopefully there'll be some way that our Inhumans connect to that ." When the film was removed from Marvel Studios' release schedule, Whedon noted that the series had "a little more freedom" and were "able to do a little bit more" with the species going into the fourth season, including the potential of introducing some of the "classic" Inhumans . Marvel's Inhumans, a television series centered on Black Bolt and other members of the Inhuman Royal Family, was announced in November 2016 to air on ABC in September 2017 . It is not intended to be a spin - off of Agents of S.H.I.E.L.D. </P> <P> The fourth season explores the concept of Life Model Decoys (LMDs), which were first referenced in The Avengers, and introduces the character Ghost Rider to the MCU . On why the series waited to begin exploring LMDs, Jed Whedon said that the series previously did not want to explore the concept before the release of Avengers: Age of Ultron, which sees the introductions of Ultron and Vision in a similar manner to LMDs . On introducing Ghost Rider, Whedon said that "with Doctor Strange coming out this year, the Marvel (Cinematic) Universe is moving into new waters," referring to the exploration of magic . "We felt that this was obviously a great character that we'd love to have on our show that we feel fits with that shift ." The season also continues storylines from the second season of Agent Carter, with the reveal that the Momentum Energy Labs group is a successor to the Isodyne Energy company, with both companies connected by the parent company Roxxon, a mainstay of the MCU . In August 2017, Emily VanCamp said that discussions had taken place for her to reprise her role of Sharon Carter for the series, but there were conflicts with her starring role on the series Revenge . </P> <Table> <Tr> <Th_colspan="2"> Season </Th> <Th> Episodes </Th> <Th_colspan="3"> Originally aired </Th> <Th_colspan="3"> DVD and Blu - ray release dates </Th> <Th> Netflix release dates (U.S.) </Th> </Tr> <Tr> <Th> First aired </Th> <Th> Last aired </Th> <Th> Timeslot (EST) </Th> <Th> Region 1 </Th> <Th> Region 2 </Th> <Th> Region 4 </Th> </Tr> <Tr> <Th> </Th> <Td> </Td> <Td> 22 </Td> <Td> September 24, 2013 (2013 - 09 - 24) </Td> <Td> May 13, 2014 (2014 - 05 - 13) </Td> <Td> Tuesday 8: 00 pm </Td> <Td> 000000002014 - 09 - 09 - 0000 September 9, 2014 </Td> <Td> 000000002014 - 10 - 20 - 0000 October 20, 2014 </Td> <Td> 000000002014 - 11 - 12 - 0000 November 12, 2014 </Td> <Td> 000000002014 - 11 - 20 - 0000 November 20, 2014 </Td> </Tr> <Tr> <Th> </Th> <Td> </Td> <Td> 22 </Td> <Td> September 23, 2014 (2014 - 09 - 23) </Td> <Td> May 12, 2015 (2015 - 05 - 12) </Td> <Td> Tuesday 9: 00 pm </Td> <Td> 000000002015 - 09 - 18 - 0000 September 18, 2015 </Td> <Td> 000000002015 - 10 - 19 - 0000 October 19, 2015 </Td> <Td> 000000002015 - 11 - 11 - 0000 November 11, 2015 </Td> <Td> 000000002015 - 06 - 11 - 0000 June 11, 2015 </Td> </Tr> <Tr> <Th> </Th> <Td> </Td> <Td> 22 </Td> <Td> September 29, 2015 (2015 - 09 - 29) </Td> <Td> May 17, 2016 (2016 - 05 - 17) </Td> <Td> TBA </Td> <Td> 000000002017 - 01 - 30 - 0000 January 30, 2017 </Td> <Td> 000000002017 - 03 - 01 - 0000 March 1, 2017 </Td> <Td> 000000002016 - 06 - 16 - 0000 June 16, 2016 </Td> </Tr> <Tr> <Th> </Th> <Td> </Td> <Td> 22 </Td> <Td> September 20, 2016 (2016 - 09 - 20) </Td> <Td> May 16, 2017 (2017 - 05 - 16) </Td> <Td> Tuesday 10: 00 pm </Td> <Td> TBA </Td> <Td> TBA </Td> <Td> TBA </Td> <Td> 000000002017 - 06 - 15 - 0000 June 15, 2017 </Td> </Tr> <Tr> <Th> </Th> <Td> 5 </Td> <Td> 22 </Td> <Td> December 1, 2017 (2017 - 12 - 01) </Td> <Td> TBA </Td> <Td> Friday 9: 00 pm </Td> <Td> TBA </Td> <Td> TBA </Td> <Td> TBA </Td> <Td> TBA </Td> </Tr> </Table> <Tr> <Th_colspan="2"> Season </Th> <Th> Episodes </Th> <Th_colspan="3"> Originally aired </Th> <Th_colspan="3"> DVD and Blu - ray release dates </Th> <Th> Netflix release dates (U.S.) </Th> </Tr>
