Sith is not the aloof type; he neither appears too quiet nor does he make eye-catching actions. From any angle, he's just a normal person.
Actually, it's good this way. Those faceless, seemingly unapproachable folks could be of any profession, any identity, but definitely not a spy.
Smile when you need to smile, cry when you need to cry.
Laughing at the wrong time can be lethal, but once in the car and away from others, one can laugh.
Before getting into the car with Gao Yi, Sith's expression was normal. But after boarding, especially when it was just him and Gao Yi left, Sith's face broke into a smile, and once the car started moving, he laughed outright.
"What are you laughing at?"
"I'm laughing at Captain Britain … hahaha … it's hilarious!"
Gao Yi thought for a moment and said, "Jeer at the joke, not the person. No, wait, we shouldn't mock others' physical defects. Obesity is an illness; it's unethical to laugh at it like that."
