Why Sylvie Is the Real Cause of 'AVENGERS DOOMSDAY'
Everything in Infinity War and Endgame was meant to happen according to the TVA. Star-Lord, Tony Stark, Doctor Strange, Wanda, and Steve Rogers were all following a timeline that was supposed to exist.
The one event that wasn't supposed to happen? Loki escaping in Endgame.
When Sylvie killed He Who Remains, she shattered the Sacred Timeline and unleashed the multiverse. Kevin Feige even confirmed that Loki and Sylvie's actions allowed the spell in Spider-Man: No Way Home to go wrong, setting the Multiverse Saga into motion.
From No Way Home to Multiverse of Madness, Monica Rambeau being stranded in another universe, and now Avengers: Doomsday it all traces back to that one decision.
He Who Remains even warned Sylvie what would happen if she killed him and offered her another choice. She ignored it.
So when you watch Avengers: Doomsday this December, remember It all started with Sylvie.
