#taking wild guesses
Okay, I’m updating my FitzSimmons prediction:
I stand by what I previously said: I don’t think this is the original or “real” Jemma. The tease in the finale of last season that it took her, Fitz and Enoch “a long time” to develop the tech for the time jumps, a few other throwaway lines - she’s a Jemma from far in the future who came back to rescue them from Izel’s temple and set them on a path to stop the Chronicoms. She’s seemingly human, based on May being able to pick up her emotions, so probably not LMD; a clone, maybe?
Fitz was 100% the guy coming down the ladder behind Coulson just before he blew up the Chronicom ship. But it’s not the real Fitz either - how could a human survive on a ship with no life support systems? “Completely exposed”; he was on that ship, sending the team the coordinates for the next jump as soon as he knew them, disguised in the body of a Chronicom or LMD.
This could explain Jemma’s freakout after having Diana removed - she realized that Fitz was in the ship that Coulson blew up, but she had no memory of it until that moment (“What have I done? I’m sorry. No!”), the same way she had no memory of programming Enoch to protect Fitz’s location at all costs. To this point, if this were, in fact, not the “real” Jemma, of course she would have no qualms about putting the importance of Fitz’s cover over the life of her replica.
I think Enoch rescued Fitz and Jemma during the assault on the Lighthouse by the Chronicoms, and they secreted themselves away, building tech that would allow them to fight the robot war. During that time, they developed tech, started a family, and fought the robot war, perhaps losing their friends, perhaps even their daughter, along the way (this could also be the cause of Jemma’s freakout because let me tell you, as a parent, there is no greater fear).
So when the Chronicoms decided to go back in time to stop SHIELD at the beginning (which ties in some nice Terminator vibes), Fitz and Jemma saw an opportunity: what if they could create replicas of themselves to go back in time, gather their friends, resurrect Coulson and May, and stop the robot war from happening? They could save their daughter’s future. Then they programmed/inhibited these replicas to forget, so they could perform the mission without distraction.
This would mean they had time, and a life together, and could destroy their copies when they caught back up to the timeline. Based on promo materials, it looks like the gang is back at the 1983/4 lighthouse in “Stolen” - maybe they can find Fitz’s hard drive among the wreckage, the way they found Coulson’s. Maybe Fitz was able to hide himself in Coulson’s hard drive (plausible especially if the person on the ladder was him; then he and Coulson would have been on the same room when the ship detonated).
So here’s the TL;DR - Jemma is not the “real” Jemma; she’s a clone or an especially advanced synthetic. Fitz is a LMD or Chronicom and his data is under the Lighthouse somewhere.
The PS is that based on episode titles, I think Fitz will be reintroduced by the end of “Stolen”, and then “Brand New Day” will be a flashback of he and Simmon’s time together during the robot war.
These are just my predictions, please be gentle in the comments.
