When Zarc had regained consciousness in his alter ego's body, he'd been confused. After all, they hadn't exactly parted on the best of terms. Even more confusing was how he had ended up there in first place. Zarc only remembered being yanked somewhere, losing consciousness and then waking up in the depths of Yuya's mind. It wasn't exactly a terrible place to be, really. Quite the opposite. Yuya never tried to lock him away or get rid of him, they barely even interacted at first. Zarc was simply left alone.
No expectations. No demands. No pressure. Even the constant haze of bloodlust that had driven him insane was gone.
It was... refreshing.
The only real problem was that he had nothing to do while floating about in the back of Yuya's mind.
So he did something he hadn't had the chance to in quite a while: sat back and watched. Just... watched.
Watched as his alter-ego lived his life, slowly relaxing, letting himself slow down from the wild pace his life had taken in the past year. Talking, recovering. Just existing without any looming threat or deadline or the weight of being a social outcast for a frankly, ridiculous reason. (Yes he had looked through Yuya's memories, so what?)
At first Zarc had been sure that the kid would end up exactly like he himself did. The similarities between who he had been and his Standard Dimension self were too glaring not to notice after all. At first it had been painful to watch. So optimistic, so determined, so hopeful, with an undying spirit of entertaining. Unlike him though, Yuya was a naturally nice person with a lot of friends who genuinely worried about his wellbeing.
Unlike Zarc, Yuya had people who CARED, so maybe, just maybe, it could be different this time.
But he wouldn't get his hopes up.
