The internet absolutely broke Thursday morning when Marvel Studios dropped a brand-new trailer for Avengers: Endgame.


Unlike the first trailer that was released in December, this one gives us much more insight on how the Avengers will attempt to defeat Thanos and restore balance to the world. And since the trailer provided these extra details, there's been even more fan theories made in the past 24 hours about the upcoming movie.


The new footage has prompted one fan to post a theory claiming that there will be major deaths in Endgame: four in particular. Posting to Reddit, user TheRealBrandini97 explains how they noticed something peculiar about the trailer.


"If you's [sic] can remember there was a theory going around that only 2 of the original 6 Avengers will survive at the end of Endgame," the write. "If you listen to the new trailer, you'll notice 4 of the original Avengers say the line, 'Whatever it takes'. The 4 that say this are Captain America, Black Widow, Hawkeye/Ronin and lastly Iron Man. Could these be the 4 original members that sacrifice their lives to save everyone?"


Citing behind-the-scenes reports, the user mentions that Chris Evans is likely leaving the role of Steve Rogers, and Robert Downey Jr.'s Iron Man is likely about to see his last days as well.


As for the two other heroes, the theory states, "The Russo Brothers said Hawkeye would have a big arc in Avengers: Endgame that all Hawkeye fans would enjoy (what bigger arc than laying down your life, to bring your family and half of all life back?) And as for Black Widow, her movie is guaranteed to be a prequel now."


It's also mentioned that the Russo Brothers said 2016's Captain America: Civil War would play a fundamental part in Endgame. "The 4 Avengers that repeated ['Whatever it takes'] in the new trailer happen to all [be featured] in Civil War while the other 2 original Avengers (Thor and Hulk) that didn't repeat the phrase, are not in Civil War," the Redditor adds.


Of all the theories out there on the internet, this one seems to be one of the most plausible. The "whatever it takes" line surely stood out in the trailer, so maybe Marvel was hinting at this being the last hurrah for Captain America, Iron Man, Hawkeye and Black Widow.


We'll find out when Endgame debuts on April 26.
