There’s a really beautiful moment in "Proportional Response" during Charlie’s interview:
CHARLIE Well, I have a little sister at home.
JOSH You take care of her?
CHARLIE Yes sir.
JOSH Your parents are gone?
CHARLIE My mom, she’s a police officer. She was shot and killed on duty a few months ago. Five months ago.
And the look on Josh’s face after that is many things but it is also the look of strange solidarity. And it totally breaks my heart.
