Use your "Inside Voices" if you try to escape from HYDRA. After Carl Creel tries to connect with the gravitonium, he confronts Coulson in his locked room, only to discover that General Talbot is being held too. Phil convinces him to get them all out, but they'll have to get past all the mechanical obstacles and General Hale's powerful daughter Ruby. They have a few tricks up their sleeves, but it may be fatal for Coulson. Daisy decides that the only one that can help them rescue the Director is their future-telling friend, Robin. But when they pick up the girl and her mother, she's not very open about what she knows. That is, until she sees May. As depressing as the future sounds, it may lead them to the boss. Back at the lighthouse, Simmons decides she needs Fitz out of his prison to help stop Hale's weapon. Yoyo agrees, but they have to get Mack to set him free. That's gonna take a little trickery, and a big gamble. Jay and Josh try to remember which glass they poured water in on this week's Agents of S.H.I.E.L.D.: Case Files.
