The team goes to "After, Before" when the Zephyr jumps uncontrollably through time. Yo-Yo may be the only hope to save them before it's too late, but she'll need her powers. So she and May take a trip to Afterlife to visit Inhuman expert Jiayang. The rest of the battered team stays on board to try to do what they can, but time is ticking away. After a few tests, they realize that Yo-Yo's trouble is mental, not physical. With May's help she'll come to terms with her past. But trouble brews outside of Afterlife when Nathaniel Malick show up and persuades an Inhuman to help him infiltrate the sanctuary. This mission is far from over as dangers seem to appear around every corner. Jay and Josh wait for their legs to print on this week's Agents of S.H.I.E.L.D.: Case Files.
