The Question
Eternal
There is supposed to be a deleted scene of Rocket telling Carol about the Benatars homing beacon, she wasn't rescuing Stark, she was rescuing the guardians, that's why Rocket looked so sad when only Nebula got off, up to that point he only knew for sure that Groot was gone.
Okay, that's a pretty good explanation for that, then. And I can allow that some scenes are cut for pacing reasons rather than for content, so I'll accept that as an answer.
