It really was freeing, being lost to music like that, she could just let go, move, she didn't have to be so focused all the time and honestly that was probably a good thing for her to learn. She knew that herself. She was in a world without Thanos. Without Infinity Stones. She was able to be herself for the first time since what happened on Zehoberi. Everything was simply wonderful until she heard it. A laugh, a man's laugh.
The laugh made Gamora spin on her feet. She'd have preferred the rich man who kept insisting on prodding her with things or the man with the arrows. Not Quill. He'd gloat. And he was already laughing.
"I was just...It was not unpleasent music." she said simply daring him to challenge her. She'd hate to have to beat him down again.
