i was wondering why does tobi just show 1 eye?then i saw it was a sharingan but if he was a real uchiha he should have sharingan in both eyes.then i heard itachi said madara uchiha then i saw him gathering sharingan and implanting them like danzos.he wanted to get his sharingan but couldnt.anyway if he is an uchiha what good are sharingans to him and why so many?it would sound more reasonable to me to say he is not a uchiha.what do u guys think?
