Did Nebula know?

There’s a interesting Quora discussion about whether Nebula somehow manipulated the Avengers into sending Clint and Nat to Vormir, knowing that they’re physically the most vulnerable and that they love each other

She says they have to “not fall out” of ... what? Hyperspace? Benatar’s pod? Or out of their mutual friendship?

Personally I think it’s a no.

But I do think they all suspected Thanos had to trade Gamora for the stone

Sure it’s possible she died trying to stop him, but Nat and Clint accepted the truth pretty readily
