As for personality-wise, I'd assume he'd have the same one as the original one considering that the Higa-copy acted the same before the "big reveal" in Vol. 10

Spoiler for Question:

Why did the copy Kirito not end up like the other copies made by Higa? Is it because copy Kirito was able to accept the fact that he is a copy?
