Plot summary
Following the signing of the Sokovia Accords, Talbot and Coulson discuss registering the Inhuman agents, with Coulson taking Talbot to the S.H.I.E.L.D. base to introduce him to Rodriguez and Lash, explain the Hive situation, and show him the need to keep the Secret Warriors anonymous. Hive captures several Watchdogs for Radcliffe's next experiment attempt; they are horrifically mutated into primitive Inhumans, but do fall under Hive's sway, prompting him to proceed with his ultimate plan—to use a warhead stolen from the ATCU to spread Radcliffe's new pathogen around the world and transform all humans into these primitives.
Lincoln contacts Daisy and convinces her that he wants to be with her. Hacking into S.H.I.E.L.D.'s systems as her blood is drained, Daisy helps him escape the S.H.I.E.L.D. base in a quinjet. However, this was a ruse on S.H.I.E.L.D.'s part, with Lash arriving instead of Lincoln. Lash uses his abilities to free Daisy from Hive's sway, but is killed by James. Daisy escapes back to S.H.I.E.L.D.
