As far as I could tell just the people who were snapped or blipped were brought back. So people that died of consequences relating to the blipped, probably didn’t come back. Just like how he could not bring Nat back.

She turned on Thanos at the end, when she realised that he was gonna kill her to get the *soul* stone I think

I think Gamora was more convinced by what the main “good” Nebula had told her of their future together. Don’t even recall the soul stone sacrifice being mentioned.

Because Nebula had not told her she only saw it when she was tortured

Tony snapped the people who were fighting for Thanos at that battle, so Gamora more than likely wasn't snapped because she was not fighting for Thanos.

And the creators confirmed that people that would have been blipped back, they would not be brought back to the same location that they were snapped, if that meant they would die if they spawned at said location. So people who were snapped on a airplane in mid-air, would be brought back to a place of safety. Same goes for people on a boat, on the top of a building that, for convenience, no longer exists, or on a spaceship, etc.

Bring this question to Quill and see what he's gonna say.

Quill? As in Peter Quill? Who do you mean and how and why?

We also don't technically know she wasn't affected. Yeah, in the deleted scene she walked away and didn't kneel for Tony, but as far as what was actually in the movie, we don't know (they could have deleted it because James Gunn wanted her to stay dead for Guardians 3).

Maybe... I believe they most certainly want Gamora to be alive in Guardians 3... so I think the most parsimonious assumption is to assume that she is alive.

Perhaps he saw that she was fighting for the right side...
