Quackity was red like fire. If Bad was too close to it, he would burn and disintegrate to nothing but ashes. But when there is this safe distance, when he makes sure that everything is okay, the fire gives off warmth and love. Like Quackity. He was red like blood, like a whisper of passion and love, but also a scream of danger. He reeks of anger and resentment, of grief and revenge. But he also gives off longing kisses and touch-starved hugs. He was both of those things. And Bad equally loved them all.
