Miller was walking around the building where Vivian does her magic shows in, not focusing on his surroundings and pushing past whatever got in his way as he had only one goal; SITTING DOWN.

Eventually, he reached a table that was empty and sat down there. Now looking far less aggressive than he did prior, it's like he had a whole mood shift once he sat down on a chair, really weird.

He subsequently brought out a cigarette throwing it towards some random spot, why'd he do that, no clue. Maybe it's something he just.. normally does whenever he's inside of Vivian's work space?
