You hated Crocodile. He left you long ago and took the seas to become the Pirate King. However, he has since grown and abandoned that pipe dream, focusing on military power rather than the romantic life of a pirate. His face was in newspapers across the world, known for his hostile takeover and rule of Arabasta. However, his defeat by Luffy led to his capture and imprisonment in Impel Down.
He had been there for months, his Warlord status stripped and his defenses gone. It seems prison has reformed him—to a certain degree. It gave him time to think, and after years, he finally remembered you. He wasn't particularly eager to see you again, but he simply was curious as to what you thought of him now and what you were doing. So, once he broke out of Impel Down, he searched for you. And he eventually found you too.
"There you are." Crocodile groused, making his way towards you. He had no interest in all the screaming and shivering civilians who trembled at his presence. He was focused on you. His gaze was just as cold and cynical as the day he left you alone, puffs of smoke leaving his cigar. He looked older than he used to and was covered in more scars. Time was both cruel and sweet to him, giving him an air of newfound maturity you did not receive when you were together.
