Avengers: Infinity War - 15 Things Marvel Want You To Forget First
2. That Thor Had The Special Stuff All Along
When It Mattered
Back in Thor: Ragnarok, the key central message of the final act was that Thor was far more powerful than he ever imagined and that the destruction of Mjolnir didn't even matter because the special stuff was in him all along and he could use his powers of commanding lightning without a conduit weapon.
That also marked his final ascension to being truly worthy, which wrapped up the entire Thor trilogy nicely.
But Now...
Apparently, Thor will decide that he actually does need a weapon after meeting Thanos and seeing how powerful he is. Which suggests that his life-changing revelation in Ragnarok won't matter for more than the thirteen minute or so it took to end that movie and have Thanos' ship appear in the post-credits scene.
That's got to be a record.
Basically, Marvel don't want that story to matter any more, because it makes Thor far too powerful and far too great a threat to Thanos. They need him to be spooked by his own limitations, which means an immediate retcon of what that whole revelation meant.
