So there are two teams in Avengers: Endgame: Natasha (Black Widow) and Clint (Hawkeye)/Nebula and War Machine.
Yet Black Widow and Hawkeye were chosen for the mission to Vormir. So did Nebula knewknow to send them since one loved one had to be sacrificed and she gathered that they both share a history or was it just a normal team separation?
TLDR: Did Nebula send Black Widow and Hawkeye to Vormir since she knew one had to be sacrificed and it should be a loved one?
