in orbit by their masters as a fail-safe in case the Inhumans rebelled against them. One of the Reapers attacks Hive, who eventually kills him in a fight, after which the SHIELD team attempt to destroy Hive with a grenade launcher, which proves insufficient. The other Kree kills Alisha before Daisy incapacitates him, and Radcliffe begins draining his blood. Mack approaches Daisy and tries to convince her to leave with him, still believing she is resisting Hive's control, but she denies it and reveals Hive's plan to transform humankind. Mack then vaporizes the captured Kree with a Hydra splinter bomb, and a livid Daisy attacks him, subduing him with her powers and beating him savagely. May shoots her to save Mack, and the SHIELD agents escape while Radcliffe tends to Hive and Daisy's injuries. Remembering that there is Kree blood inside her from the GH325 injected into her after she was shot by Ian Quinn, Daisy offers to let her blood be harvested.
