I call these three chapters the Soul Stone Chapters, or the Vormir series.

Yeah, each dimension is when the OCs have to die for the Soul Stone in Endgame times,

This one is when Olivia has to yeet herself, despite Loki's protests. Her's is really close to how Natasha died in Endgame.

Loki has a hold on her, then after assuring him it's okay, Olivia pushes off and falls before Loki can do anything.

He manages to save her purple cape before she falls, however.

Now, something I had happen in these chapters probably bends the Soul Stone rules, but screw it. My dimensions, my rules.

After dying, the OCs end up in Valhalla.

Olivia in this case finds Frigga (cause 419 branch means she's long dead) and finally meets her long deceased parents. It's a really bittersweet moment.

Also, something Shipsrlife2 were developing is the idea that back on Earth, after the Avengers Vs. Thanos battle, the loved one the OCs leave behind snaps instead of Tony.

Again, as it's only a developing idea, we only have a solid idea of how it would go with Loki, as descrived in this text message to Shipsrlife2:

Idk, it was a thought.

***

As with any of the Soul Stone universes, they hinge upon both sides of the corresponding OC couple surviving Infinity War and going to Vormir.

(Don't ask me how Loki survives, just assume he does as always)

It's angst abound for these dimensions lol
