Re: How every1 Gained the SHARINGNA + MAGENKYO SHARINGAN!
He was referring to how Kakashi got the Mangekyou Sharingan. We don't know how Kakashi got his, but we can assume that he didn't kill his best friend. Why? Because he stated himself that all the people close to him had died, and right now Gai is probably his best friend, but Kakashi didn't kill him. So we can assume that he either trained to obtain his Mangekyou Sharingan or found some other way, like finding scrolls that held the knowledge of the Sharingan or some other crazy theory.
