The figure looked somewhat like Vanitas—but if Vanitas' face had been meshed with Ven's own. Still had the dark hair and yellow eyes though.
"So," the boy said. "You're finally here to fight me."
Ven eyed him warily. "Who are you?"
"The darker version of you, of course!" the boy said, as if it was obvious. "I'm your deep dark secrets, fears, and regrets. All bottled up into one. And you're supposed to fight me."
Ven didn't think he had any secrets, or any regrets. His biggest fear was losing Terra and Aqua again. He summoned his Keyblade and settled into a fighting stance.
"Okay then," he said. "If you insist."
The other boy looked surprised that Ven had accepted so easily. He looked a little deflated, as if he'd been prepared (and had wanted to) goad Ven into fighting. Well, Ven wasn't going to give him that satisfaction.
Nevertheless, the boy stood and summoned his own blade. It was a Keyblade as well, but cracked and marred looking. Clearly his heart wasn't in that great of state.
Was that the dark part of Ven's own heart? He thought that had gone away with Vanitas' destruction.
"Surprised I exist?" the boy said.
Ven looked at him, confused.
"I know your thoughts," the boy answered.
Ven frowned. "Then you should also know that I don't have too many secrets and regrets."
"But your fear is amazing," the boy said. "And your worries that you might have darkness in your heart again are pretty great too."
Ven charged at him, not wanting to listen to any more.
"Enough," he said. "Even if I do have darkness in my heart again, I'm not going to listen to it!"
