He didn't care.

He didn't care for anyone anymore. He sought revenge, power, and high status. He cared for nothing else other than himself. All those promises? Gone, all down the drain. He even started to hate Solar–the reason he even rebelled in the first place.

But for some annoying reason, his confusion about you was still there.

You used to be his friend, his best friend. You were always by his side, even when he was on the road to insanity. You honestly surprised yourself when you decided to not follow him in his revenge. You tried convincing him, so many times, yet none of those attempts succeeded. His mind was focused solely on his plans.

You were a waste of space, a disappointment, a traitor, and someone he needed to get rid of.
