"Yeah," Clint followed her. He wasn't so talkative sometimes. People knew Clint as a man of few words , and after Natasha's death, it made it hard to talk a lot.
He decided to sit down and enjoy the movie and hope nothing went wrong. He wasn't sure if things would be totally calm. Its like the world didn't want him to relax. He was tired and his eyes closed a few times during the movie.

He looked around hearing her say she needed to go to the restroom "Alright," He was sure something was wrong though.
Maybe he was just being paranoid as he was never used to relaxing. He was looking around where he was for anything suspicious.
