Tightly related to other questions:
- What was Coulson doing at the bifurcation point, in the looped branch of the timeline
- When was this character supposed to die in the looped timeline?
This whole question is going to be spoiler heavy up to the end of season 5. I've only spoilered the very biggest shock - the majority is openly discussed.
What we can observe
So, shockingly, they managed to break the time loop. I know... who would have predicted that?
We know that in both loops Daisy leaves the Quinjet and shouts something at another occupant before she walks away. (We infer that Coulson was inside it in both timelines.)
We assume that in the looped timeline, Talbot and Daisy fight, Talbot overpowers Daisy, and Talbot absorbs her and then shatters the Earth.
Robin specifically comments on the timelines having diverged, but she does so whilst going down the stairs with her mum, i.e. after Mack goes into the ship, and after Fitz and May follow him in to help, and after Mack leaves with her mum, while Fitz and May stay behind to fight the last Remorath soldiers.
Fitz is killed by a rubble-fall
caused by Talbot slamming Daisy into the ground from a great height, but that happens before Daisy takes the serum.
The change point is implied to have been Coulson's decision to not take the serum, but that doesn't start to change Daisy or Talbot's behaviour until the point at which she notices the serum in her glove.
i.e. after Fitz has been mortally wounded.
Question:
It seems to me that Fitz must have died, in the same way, and at the same time in the looped timeline.
Is there any other possibility?
If that's the case, how does Deke come to be born in that timeline? Are we supposed to infer that Gemma is already pregnant?
Is there anything else that would appear to contradict this event happening, in this way, in the looped timeline?
