Take a good look at this face. This is the face of a woman plotting. This is the face of a woman who knows shit is about to go down, and she’s in a terrible position for it. Luke is about to unleash hell, but Jabba has Leia on a leash - all Jabba would have had to do is say “Stop attacking or I snap her throat right now” and the day would have been lost.
This is the face of a woman who is not about to let herself be used like a pawn. Not about to be the damsel in distress. This is a woman plotting HER move in this game, irrelevant to what the boys do. A woman who takes her life into her own strong, capable hands and honestly is the only reason any of this worked at all.
