Both shisui and Itachi seem to have gained their MS around the same time.
How is it that they did it without killing eachother?
The manga hints they were best friends, and Itachi lied by saying that he killed his Best friend(Shisui) but shisui killed himself after he gave itachi his MS.
If itachi did kill shisui(after he got MS-Shisui) then how did shisui get HIS ms?
Also, if shisui was itachi's mentor does that mean shisui is stronger than Itachi?
