KakashiObito MS Theory
I don't know if this thread was already made in the past.
But my theory is MS are inter-connected.
The moment Obito saw that Kakashi killed Rin,he gained MS.After a short while OR at the same time,Kakashi gained MS too.
After that,Kakashi faints because he does not have an Uchiha body.
Well,in the theory of others that Kakashi have a weak bond with Obito,I can say that you have to kill your closest/special
someone in order to gain MS.Kakashi did not kill Obito.And besides,Obito did not die.
