Tye arrives and Hek-Tel gives Kasius the Seer's sketches from the ship. Kasius realizes that his Seer has said the team would come from the past, and if they're there then they haven't destroyed Earth. He then tells Tye that Kasius' father called Earth a blue gem, and tells him to gather a fighting force of Inhumans to crush S.H.I.E.L.D.. Once they're dead, his father won't encounter any resistance in the past when he comes for Earth.

Future-Elena says that she went through the same experience from Elena's point of view, and explains that the Kree killed her and then brought her back, again and again, when they need her. She explains that she tried to give them as little information as she could about the team, and smiles as she remembers that Mack is still alive. Future-Elena tells Elena to hold onto Mack as long as she can, and says that they make it back in time but bring everything that's to come. Elena doesn't believe it, and Future-Elena says that she didn't either until she was on fire reaching for Mack. When Elena asks how they can change it, Future-Elena warns that she can't.

Mack assures Flint that he can handle it, and Fitz apologizes to Mack for having to kill the soldiers. He explains that Jemma was the one who came up with the plan to shatter the viewport.
