Chang and son
Wonder what Pierre Chang thought of his adult son?
That’s the problem with inscrutable orientals (or racist clichés for that matter) … When he looks Miles over after the latter admits that he is from the future he does not let a lot of what he is thinking through.
Hope they have more scenes together. My thought is that it is Miles’ voice we hear on the video when Chang describes the purge, not Daniel’s. I know I am not reaching very far when I am saying that, but…

We will probably have more scenes with both of them together.
Now that Miles saw that his father was trying to save both his mother and him, he will want to spend more time with his dad.
… Before good ol’ dad dies in the incident, or the purge…
