Garrett's jet is attacked by S.H.I.E.L.D. drones after the Bus is hijacked, and he rejoins the team. At the Hub, Simmons and Triplett begin working together to secretly upload Simmons's research on Skye's blood, only for a Hydra assault on all S.H.I.E.L.D. facilities to force them into hiding. Coulson locks May in the interrogation room with Ward, still believing she is the traitor. Skye discovers a secret code in a signal on S.H.I.E.L.D.'s network that she deciphers to reveal Hydra's infiltration. When the Bus arrives at the Hub, the group splits into teams to capture Hand. However, Hand reveals that she is not a member of Hydra but believes that Coulson is, and recruits Triplett and Simmons to aid her in stopping them. Garrett accidentally discloses information that reveals himself as the true Clairvoyant, and is captured by Coulson and May.
