find Radcliffe, under the guise of geneticists wanting to sell him eye prosthetic technology based on those used for Project Deathlok. Upon meeting Radcliffe they reveal their true intentions and ask for his help to devise a cure for Hive's infection, but they are interrupted by the arrival of Hive himself and his Inhuman allies. Alisha abducts Radcliffe, while Daisy subdues Fitz with her powers and warns him of her vision of an agent's death, wanting S.H.I.E.L.D. to stop trying to combat Hive, and avoid that future from coming to pass. Mack narrowly escapes James, and Hive approaches Simmons, speaking to her as Will, using his memories, only for her to shoot him and escape, after deriding him for trying to be someone he murdered. The three agents reconvene at a hotel, where Fitz and Simmons finally consummate their relationship while Mack "goes to the quinjet" (purposely leaving them alone for a while). Under Coulson's direction, Talbot and the ATCU use information Malick provided before his death to neutralize what is left of Hydra, with the exception of the forces commanded by Hive. So all HYDRA facilities, buildings and stations are bombed and destroyed, with Coulson and May looking on, satisfied. In an end tag, Hive brings Daisy, Radcliffe, Alisha, and James (who has chosen the moniker 'Hellfire') to a town he bought with Malick's money. Seeking to make Earth 'the home Inhumans deserve', he reveals his intention to recreate the original Kree experiments and convert the entire human race into Inhumans, with Radcliffe's medical and scientific help.
