Coach:

He leaves it to you but he won't be too happy about it. Rarely talks to them, crossed arms, almost glaring to them, comments like "keep up", "can't you do that?", "don't do anything stupid".

Rochelle:

Without realizing she's cold to them, keeping a constant eye on them, suspecting they'll do something but up to you to throw or take them. If you don't accept them in the group she just walks past them. If you do accept she'll tell them "you better don't try anything".

Ellis:

If they were bad to you: then that is his worst enemy who he is ready to shoot or smack with his meelee weapon the second the chance is there. If they were good to you and ended it on good terms: best buddies who will now discuss what it is like to date you and bond over it.

Nick:

He's got a gun, he plans to put it to good use. If you tell him to stop it he will but not be shy to loudly insult them. Indirectly but mainly direct. He might even look at them and insult them to their face.
