Plot summary
At dinner with Coulson, Price reveals plans to confront Malick, before being abruptly sniped by Ward and dying in Coulson's arms. Promoting Mack to interim director of S.H.I.E.L.D., Coulson sets out for revenge and goes off-book with Hunter and Morse to kidnap Ward's younger brother, Thomas. Fitz and Simmons go with Banks to investigate the ATCU, but Banks is killed and the other two are captured by Hydra. Simmons is tortured until Fitz agrees to help Hydra return Hive to Earth, while Coulson uses a phone call between the Ward brothers, where Grant attempts to justify himself and his past actions to Thomas, to locate Hydra: they have set up base at the English castle.
Mack clears Gutierrez and Lincoln for field duty and mobilizes the rest of S.H.I.E.L.D. for a rescue mission. Hydra reopens the portal and Malick convinces Ward to lead Hydra through it with Fitz and return with Hive, promising that Coulson will die when they return. Determined to kill Ward, Coulson manages to enter the portal as well.
