You are right in that Mono is paired with quiet people, who don’t had any voice nor ability to express their thoughts and feelings.

With what little we know about Mono’s character, this might be 100% intentional. Thin man’s real life counterpart. The Broadcaster refers to his broadcast/himself as the “voice of the counties”, but with little we’ve heard of his program he host already well-known individuals such as The “famous” Doctor (implied to be the one in LN2)

People who don’t need a plataforma nor more exposure and of which endorsement can be actively harmful to society (he is a quack and one of the reasons for Noone’s decline in physical and mental health and what he said in the program almost pushed Myra into suicide).

In retrospective Mono getting paired with a neglected kid who doesn’t have the ability to speak up nor express her feelings. The one person who needs to be need and Mono committing the mistake of shushing her when she was looking for support. Is so in line and ironic to the self proclaimed “voice of the counties”.

With that said I don’t believe Mono nor the thin man to be a inherently bad person. He is far more flawed and complex than people give him credit.

And Chief downes confirms residents are not just monsters. They were desperate people who where shaped by their society and ended up doing awful things. I really loved Homer because Myra pov painted her as a very human and sympathetic person

Though him abandoning Hush at the beginning of DTN is a bit different, it isn't one of those situations were its "do or die" He's making the decision to run. Though I don't think Mono necessarily left Hush in the middle of danger. She's fine under that bench so long as the Jailer doesn't know she's there. Mono doesn't run until the Jailer has finished looking at Hush's empty cage and has walked infront of the bench. Whether or not the Jailer was going to look under or not isn't clear, but I think Mono is under that impression. I think he's got the idea of "she knows, we've basically been found, now is the time to run". I don't think Mono—who's been stated to have been in the nowhere for awhile at this point, and understand how to survive—would run out infront of the Jailer instead of doing it while she wasn't looking. He'd be fully aware of the fact she's going to see him and chase him, but I definitely don't think he's intentionally making himself a distraction for Hush to get away either. I don't really think he'd be under the impression he's leaving Hush in danger.
