The official Instagram account for Marvel in the United Kingdom has posted a timeline of the Soul Stone's journey within the MCU. Check out the following slides:
This timeline begins with the creation of the Soul Stone and the other Infinity Stones, just as Wong explained in Avengers: Infinity War. From there, the image shows the Soul Stone being housed on Vormir, followed by the Red Skull becoming its keeper due to his actions in Captain America: The First Avenger.
Following the point where Gamora discovers the location of the stone, things get a little messy.
While Natasha Romanoff sacrifices herself in 2014 amid the Avengers: Endgame time heist, in an alternate timeline, Captain America returns the stone.
The timeline then shows the point where Thanos sacrifices Gamora, obtains the Soul Stone, and then snaps away half of all life. Still, it's important to remember that, even though this happened in 2018, it technically occurred before the events of Endgame and Nat's sacrificial death.
This trajectory comes to an end when Thanos uses the stones to destroy the stones at the beginning of Endgame.
However, the timeline which began when Nat sacrificed herself continues, leading up to the Hulk using the stones to reverse Thanos' snap in 2023. Also, Cap's timeline where he returns the stones is present as well.
Finally, after the Hulk's snap, the Soul Stone is used once more by Tony Stark in Endgame to destroy Thanos and his army, all before it's given to Captain America to be returned to 2014.
Meanwhile, in a separate timeline? Reality? Universe? The visual shows an alternate version of the Infinity Stones being used as TVA paperweights from Loki on Disney+.
