My impression was that Gamor died when Tony snapped Team Thanos to dust because Gamora, who just made nice with her sister, wasn't at the funeral, AND Quill is looking for her in space (how would she have gotten off the planet?). I figured they were tracking Gamora that was no-longer killed by Thanos.
BUT... Banner's snap only reversed what happened immediately after the snap, and nothing that happened in the 5 years since, so that would mean Thanos still kills Gamora. Online sites and a few posters (
@GoldenAzazel,
@Dragonlordxxxxx ) say that 2014 Gamora went off on her own after the battle. They are probably right, but so am I just because.
