Kakashi's Sharingan The Mystery Solved!!!

at the beggining kakashi was a jerk, but obito had to die so he could learn dat lesson...how sad!
But look at kakashi after! he iz so cOOl!
he looks so hot under the mask! i know this has nothing to do with this but now if u dont mind, i will tell u how i think he got his sharingan.
he doesnt have the uchiha blood-line so he couldnt have had it when he was born. wat i heard was when obito died, rin did a surgical implant by taking obito's sharingan and putting it in kakashi. i dont know the rest but i think that covers it!
Yep, its really sad... and thought of it, in the begining Kakashi says to "team 7" exatly the same words that Obito said to him:
Of course those in the ninja world who break the rules and regulations are called trash. But those who don’t care about their companions are... even worse trash.
