Avengers: Endgame - 15 Biggest Rumours From 4Chan & Reddit Supposed "Leaks"
10. Thor "Saves" The Asgardians
The Leak
According to that same comprehensive "leaked" breakdown, Thor has a major sub-plot that involves him heading off to space and finding what remains of the Asgardians. Also, it seems that they'll all be alive because they were already depleted too much by the Decimation. Which is a rare win for them.
Response
There's definitely a chance that we're going to see something about the Asgardians. Even the trailers have suggested that the survivors will move on (apart from Cap, who struggles, naturally), which would certainly turn Thor's attention back to what he was doing before Thanos turned up.
That likely means he'll be going to collect the rest of the Asgardians, which would also fit with Valkyrie having her own character poster. So this one MIGHT actually have legs.
