Plot summary
Radcliffe's first attempt to turn humans into Inhumans fails, as he requires Kree blood. Fitz and Simmons attempt to combine their potential Inhuman cure with what they know of Radcliffe's research, but require an Inhuman test subject; Lincoln volunteers himself, severely compromising his immune system and seemingly proving that the cure cannot free the Inhumans of Hive's connection. S.H.I.E.L.D. locates Hive's town; Mack and May lead a team to hopefully free the others by simply killing Hive. The latter activates the Kree artifact, a beacon which calls two Kree reapers to the town.
They promptly murder Whitley. Daisy and Hive each confront a reaper, with Daisy managing to begin harvesting hers' blood until the process is sabotaged by Mack. Hive, not realizing this, destroys the other reaper. Daisy attacks Mack, nearly killing him, but is interrupted by May, who helps Mack retreat with the rest of their team. Daisy then offers her own blood as an alternative for Radcliffe's experiment, as it was recently infused with Kree blood.
