People spend so much time leaking (or flat-out making up) things for every MCU movie these days that they deserve some attention. And the simple fact of the matter is, these leakers are often so perceptive and so creative that they do occasionally get things right.
Whether that's through legitimate insider knowledge or they're just good at analysing footage and putting two and two together remains to be seen. For anyone not yet sure on one particular theory though, no Thor won't be eating Goose and getting fat. Fat Thor is not a thing.
If only to celebrate the zaniness of the fanbase and their commitment to the gimmick, let's look at the best (and worst) of what has been "leaked" so far...
15. Loki Will Return
According to one "leaker," that line from Thanos about there being "no revivals" for Loki after he killed him, Tom Hiddleston will actually beat death once more and will play a role in Avengers: Endgame.
He's actually mentioned in a couple of leaks - sometimes as explained by the existence of Hel and Valhalla, sometimes just pulled out of nowhere - but the most compelling suggests he's in the post-credits reveal. For what reason, the leak doesn't say.
There actually IS a chance he'll be back because Asgardian lore suggests it's possible. There was also a storyline cut from Thor: The Dark World that would have confirmed that Loki actually died but escaped Hel, offering precedent for a return here.
Hiddleston does have his Disney+ TV show coming, so there is a possibility.
