Plot summary
Daisy and Lincoln unite with Gutierrez and Rodriguez as the Secret Warriors and infiltrate the Hydra base to free S.H.I.E.L.D. Gutierrez kills Lucio in the process, while Lincoln captures Malick. During questioning, Malick explains to Coulson that Hive can infect the minds of Inhumans, warning him against trusting any of the Secret Warriors. Simmons confirms from an autopsy of Lucio that Hive parasites had infected his brain and the same could have happened to any of the Secret Warriors. When Malick is found dead, the human agents trap the Inhumans in quarantine and search their belongings.
They discover the Kree device in Lincoln's possession rather than in asset lockup; Lincoln protests, but the other three are released. That night, Daisy visits Lincoln and offers to break him out. Lincoln refuses when he realizes that Hive is controlling Daisy and used her to murder Malick and frame Lincoln. Daisy leaves on her own, creating an earthquake to destroy the S.H.I.E.L.D. base with everyone inside.
