Insidious's Links
Ruby is on the verge of being insufferably sweet, but it's a kindness that Insidious has never quite gotten the chance to experience before. He holds onto it, and he grows to like him. That like turns to something more before long, and Insidious wants to protect that fuzzy feeling that Ruby gives him. It's unlike anything he's experienced before, and he comes to love him deeply in time. Ruby is kind. Ruby forgives and forgets. Ruby makes him feel whole again instead of damaged goods, and Sidi clings to that like it's his lifeline.
Insidious is big, strong, fast, and brave. He's everything that Ruby wishes that he was, and so he idolized him for a long time before they ever even met, keeping up with events around the world. When Insidious came to live with them, Ruby was astonished and was quick to make his companionship. He found him to be even kinder and softer than he ever imagined him to be before, and grows attached. That attachment forms to a deep adoration, just as strong as that which he feels towards Coach.
Coach made Insidious feel strange things from their first informal meeting. Rivals from the start, that's never truly changed. He'll still make contests out of little things, but it's in good fun anymore. He took a long time to recognize what he felt for Coach, and though it developed slowly, it developed into something truly unshakable.
Coach couldn’t stand Insidious for the better part of his life due to their vicious rivalry. After he was injured by an accident arguably caused by Insidious, he despised him even more and blamed him for ruining his life. After healing and time, things changed and they eventually grew close.
