in the final scene Carol Danvers is facing Thanos and he manages to knock her to the ground and is standing over her grinning. he's about to do a killing blow then the kid from Iron Man 3 suddenly shoots him with a nerf gun just long enough to distract so Carol can recover and kill Thanos
I'm gonna be really disappointed if she's the one to kill Thanos. It really should be Thor or Hulk or somehow Iron Man. One of the original heroes, especially if it's one that's leaving after Avengers 4
I've actually got this idea that at the end of the Captain Marvel movie, it'll show her getting snapped/disappearing, but putting up a fight to resist it somehow And during Avengers 4, She'll be the one to find a way to bring herself/others back
I have a feeling she's been raising Hulking, Mar-Vell's son. ---
