So, this is how the 2019 time travel is a loop while 1931 is not, it is clearly the split. Key things:
Quantum Realm.
<p>The Quantum Realm can be used to time travel and dimensional travel. If it is used to time travel within the same timeline, you will create a split: Barton, 2012, 2013, 2014, 1970 and 1949. So if you move from 2023 of your timeline to other ages of your timeline, you will create an instant split.
</p><p>But if you move between timelines, you won't create a split. Fitz moved through the Quantum Realm from 2019 of the MCU timeline to 1983 of the new timeline. His arrival to 1983 did not create a split because he moved between universes.
</p><p>As the 1931 thing is a split, shouldn't be the travel from c.2025 to 2019 be one too?
Yes. But Fitz-Simmons were able to create a loop to prevent that mixing time travel and dimensional travel.
</p><p>If Cap B from universe B travels from 2023-B to 1949-A, then he will not be creating a split, but he will have always be part of the story of the past of universe A since 1949-A.
</p><p>The agents did that by moving from 1983 of Alternate reality to 2019 of the MCU reality, therefore as it was dimensional travel, there were always going to be agents of S.H.I.E.L.D. returning to 2019, and the fact that they were able to return to 2019 and have always been part of it, is due to the time travel Fitz-Simmons made from c.2025 to 2019. They created their own time loop to avoid creating a split in 2019.
</p><p>So we have this:
</p>
- 2019: Fitz-Simmons go to hide and by c.2025 they have finally finished what they needed to do according to the time stream.
- c. 2025: Fitz-Simmons time travel to 2019, it should create a split, but they played with dimensional travel (which does not create a split) to ensure their time-travel from 2025 to 2019 does not create a new timeline.
- 2019.
- Fitz-Simmons arrive from 2025 (time travel it should create a split)
- Agents of S.H.I.E.L.D. from 1983 new timeline arrive to 2019 of the MCU by dimensional travel, therefore they always were meant to be part of the 2019 storyline becuase they used dimensional travel
- So the team could return by dimensional travel and have always been part of 2019, Fitz-Simmons should have ALWAYS time-traveled from 2025 to 2019 without creating a split.
<p>That is why there is not clean split in 2019 when they time-traveled, they were smart and ensured themselves to have always been part of history.
</p><p>2019 time travel to 1931, the timeline splits and there is now two universes.

<p>I like this. And it keeps AoS consistent with Endgame. But how does Runaways fit into it, since they actively rewrote their own timeline?
