Whoever went in never came out, Percy knew that, that was why he pushed you down the stairs and ran up to the golden throne and sat as the throne slowly engulfed him.
Half way through, he saw you come back, a panicked look on your face, oh how he hated seeing you in this state. Soon enough all his body was gold, he had a chance to stand up and save himself but he didn't, he couldn't.
It was odd that the starting of whatever you two had was pure annoyance, he could have never thought that he would sacrifice himself two times for your safety.
As you cried out for him on the door, the only thing left from being gold was his face. "Its okay, I'm okay." He reassured you, smiling a little, a bit of tears welling his eyes, his brows for once where relaxed, he's accepted it.
"I'm okay." He whispered, repeating his words. "I'm okay."
