Miles and Jacky : only met Miles when he was attempting to leave the asylum. He was mostly scared of him when they first met, but he relaxed, attempting to find a escape with him before they split up. He now wonders how Miles is now...
Waylon and Jacky : co workers, friendly. Jacky usually talks to Waylon whenever he came into work or during his breaks, he didn't like much other people at work anyways... Waylon felt "normal" to him.
Eddie and Jacky (yumeship related) :
"Married", Jacky usually calls him husband, hubby, or idiot. He is mostly tense with Eddie half the time, but he doesn't mind the title of "wife" much.
Eddie and Jacky (non yumeship related) :
More so acquaintances in a way. Jacky when he wasn't at the desk would usually wonder, and sometimes visit Eddie, just wanting to watch him. They don't speak much often.
