In a post credits scene, Nick Fury shows up at Cap's apartment. After they both eat some shawarma, Fury gives Cap the Aether and tells him to keep it safe. He then begins to tell Cap a lengthy story about how he almost died, but Cap falls asleep. Fury then leaves the apartment and walks out into the street. Suddenly, a car rips its way out of a dead Kaiju's stomach and runs Fury over, killing him. Jason Statham gets out of the car and calls Cap on his cell phone, leaving him a message: "You don't know me, but you're about to".
ATTENTION: The rumor about WB's "no jokes" policy is 100% correct. No one should ever doubt any rumor about any upcoming movie, even in cases where it contradicts rumors that have previously been reported. In those cases, both rumors are true.
