I remember that Itachi told Sasuke the only way to get Mangekyo Sharingan is to kill your family or your friend. How did Kakashi get his Mangekyo Sharingan all of a sudden? I think it's because of Madara using Obito's body (not saying Obito is Madara). Kakashi's eye ability is to suck things into another dimension just like how Madara suck people in with his Sharingan. The only difference is that Kakashi is not a real Uchiha so he can't use his Sharingan like how Madara uses his. I think Madara or someone is using Obito's body and that's why Kakashi's Sharingan upgraded without him killing anybody close to him. That's the only explanation to it and it all connects too. Correct me if I'm wrong.:flaw:
