Is "The Honeymoon" over, or is it just beginning? Team FitzSimmons infiltrate a HYDRA facility to prevent Hale from using the gravitonium. But Ivanov is there, guarding the place, and he may be too much for even Yo-Yo to handle. Talbot and Coulson try to stay alive in the mountains while they wait for Daisy to come pick them up. When she does, they barely escape from Ruby after a dangerous battle that leaves Deke fighting for his life. Mack does his best to save Deke, but with Simmons gone, his chances are slimmer. Hale locks her daughter up for betraying her, but Von Strucker helps Ruby understand how her mother is holding her back, and that's when they make their move. Jay and Josh miss the days when honeymoons meant a trip to Niagara Falls on this week's Agents of S.H.I.E.L.D.: Case Files.
