I like the detail where Bastion is apparently working as Mei's assistant
Indeed and I love it. After all Bastion is living outcast life away from human civilization in order to not engage in unnecessary conflict and Mei is traveling all around the world to search and study the reason of drastic climate changes. I bet both of them learn much from each other since their path is crossed in the palm of mother nature.
Also is Tracer giving Winston a peanut butter flavored banana? That's very considerate of her hehe.
