History Recap / AgentsOfSHIELDS5E8TheLastDay

* CallBack: Among the goodies Fitz hid in his storage crate are splinter bombs, not seen since several seasons ago.

* ForegoneConclusion: The {{Flashback}}s[=/=]{{Flash Forward}}s indicate the team will succeed in travelling back in time.

* DiedInYourArmsTonight[=/=]BigSleep: Robin agonizes and dies in May's arms. As she experiences time in a different manner, she barely even acknowledges the wound and treats it as if she's going to sleep, because from her perspective, she is.

* KilledOffscreen: The {{Flashback}}s[=/=]{{Flash Forward}}s imply Mack dies at some point. Elena makes a LastStand against the Kree, alone, understanding that their goal is to enslave the people in the Lighthouse. Fitz also mentions Simmons being killed. There's no mention of Daisy or Coulson after the world is destroyed, implying they also die at some point. Later, Fitz is also not shown, implying that May was[=/=]will be the last of the team to survive.
** Voss also killed Deke's father at some point.

* StableTimeLoop: We are treated to a series of flashbacks of young Robin with the team, who already know about Flint and Voss, indicating that it is a FlashForward from their perspective, after they've already returned from the future. However, Robin implies that the loop is not actually stable, and that they're doing things a little bit differently every time, inching closer to finally saving the world.
** WordOfGod explains that those scenes are from the original timeline when Enoch never abducted them from the diner.

* GladToBeAliveSex: After everything they have been through since the beginning of the season, Fitz and Simmons waste no time doing this after they have a moment alone.

* {{Foreshadowing}}: Robin keeps repeating that this is "the last day". In actuality, it is the last day of her life, after being killed by Voss.
* GladToBeAliveSex: After everything they have been through since the beginning of the season, Fitz and Simmons waste no time doing this after they have a moment together.

** We are led to believe that Robin is a little loopy after continuously calling May Mom. Turns out there was a real reason to do so.

* KilledOffscreen: The {{Flashback}}s[=/=]{{Flash Foward}}s imply Mack dies at some point. Elena makes a LastStand against the Kree, alone, understanding that their goal is to enslave the people in the Lighthouse. Fitz also mentions Simmons being killed. There's no mention of Daisy or Coulson after the world is destroyed, implying they also die at some point. Later, Fitz is also not shown, implying that May was[=/=]will be the last of the team to survive.

* WhatHappenedToTheMouse: We don't know what happened to Coulson or Daisy in the original timeline. Daisy disappeared just before the Earth was destroyed, and Coulson goes without mention.

* KilledOffscreen: Mack is implied to have died at some point in the original timeline, and Elena decides to go on a suicide mission against the Kree, something that we do not see. Simmons was also killed at some point, though this is a vision of the future as opposed to having happened in the past. Given that we have no idea what happened to Daisy or Coulson, they may have met their ends offscreen as well. At some point, both Fitz and May eventually meet their ends but the episode implies that May was the last of the team to survive.

* StableTimeLoop: We are treated to a series of flashbacks of young Robin with the team, who already know about Flint and Voss, indicating that it is a FlashForward from their perspective, after they've already returned from the future.

* DeathSeeker[=/=]DespairEventHorizon: In a flashback, Elena decides to attack the Kree rather than give up her freedom, and since Mack is gone she's lost hope that things can be set right.
* {{Flashback}}/FlashForward: A weird combination of the two. First, we see a series of flashbacks detail roughly how the Lighthouse came to be. May, Elena, Fitz, and Simmons retrofitted it to house the population, and eventually accepted the help of the Kree to make sure humanity would survive. It's eventually discovered that this group did try to get back to the past from the future to avoid the catastrophe that destroyed the world in the first place, and that the flashbacks were actually efforts by the remaining team to try to sow things for the future. See also StableTimeLoop.

* ChekhovsGun: The white monolith apparently left a piece behind that is used in a machine that will link with the monolith in the past.

Simmons was also killed at some point, though this is a vision of the future as opposed to having happened in the past.
