There were moments when Cherubimon's natures warred with one another, when his virus side struggled against his now-hidden vaccine side. It didn't happen often, now that he's moved to the Dark Continent, but those struggles existed. When they happened, when Cherubimon found himself struggling with his ideals and motives, and his coloring seemed to get a little bit brighter, Cherubimon was drawn into the Light Room, where he kept his prisoner. Where he kept his friend. That was what she claimed, anyway. Sometimes, Cherubimon found himself believing her; he missed having friends.
Then he would remember it was those same friends who ignored him and shunned him, who left him out and laughed behind his back. Those same friends who betrayed him and attempted to destroy him.
No, Cherubimon did not need friends, he needed followers and people to do his bidding, not "friends."
Still, whenever Cherubimon felt less than stable, he almost consistently found himself in that room, gazing up at whom he once thought to be his best friend. He'd had the most faith in her, in her caring and wisdom and love. And perhaps that was why he couldn't just destroy her like he had tried that other one. Cherubimon had Ofanimon imprisoned because he didn't trust himself to destroy her, because he loved her. Loved her and her brilliant smile and her soft skin and her passion and her power. He loved how she had always seemed concerned for him and taken care of him as they grew up, and those memories just didn't seem able to eclipse Cherubimon's sense of betrayal. It was a sign of weakness, he knew, but wondered if maybe he could afford this much? He had the Digital World exactly where he needed it to rebuild it the way he wanted. Surely, he could have this one thing?
And perhaps, when his job was complete, and the Digital World was fixed the way he wanted, Ofanimon would see him as her equal, and finally return those feelings.
