Coach:

When leading a group of odd survivors happens, them having their own unique habits is expected. But some habits are more nervewracking than others. Like listening to music WITH ZOMBIES NEAR!

At first he always asked of you to take them out, to be high alert, all that stuff but when he realized you work better with music in he decided to let you be. When others gave an odd look to you with your music in he just tells them to ignore it or "their thing" in a dismissive matter.

So if you die he can at least say "I tried".

Rochelle:

Stresses her the fuck OUT! Also makes her paranoid the zombies will have such good hearing they'll hear whatever you are listening to. A sweet gesture when you pull one out and hold it to her, but no thanks. She likes to hear her surroundings to avoid death.

Ellis:

Of course he wants to know what you are listening to, if you have games on there, if he can listen, if you certain specific songs. So can be found huddled together a lot; one earphone in your ear, one in his and both staring at the screen discussing whatever is on there.

Nick:

You must truly be an insane idiot... He's very blunt so he plainly said his thoughts on this. But you just stared so he glared; "You aren't even listening", which made you point to your ears and shake head as your music was blasting over his complaints. So he doesn't complain anymore.

That's a lie. Nick always complains. Now even more since you can't hear it so no one to tell him to shut it.
