Closing Notes
Obito, mentioned by Kakashi several times earlier in Naruto, is revealed to be a member of the Uchiha clan. But, unlike other noteworthy Uchiha including Sasuke and Itachi, Obito initially appears to be like Naruto in behavior, personality and ninja ability, while Kakashi is the acknowledged genius and leader of the group. Obito initially appears without the Sharingan ability. He then later awakens it when Kakashi saves him from a Rock village ninja.
The gaiden also explains the origin of the scar on Kakashi's left eye. In the earlier arcs, it was believed that Kakashi's left eye scar came from the surgical implantation of the Sharingan eye. However, in chapter 242 of the Naruto manga, the scar on Kakashi's left eye appears now to have come from a battle with a Rock ninja. Kakashi detects a Rock ninja, and yells his warning at his teammate, Uchiha Obito, who is too slow to react. Kakashi jumps in front of Obito to save him from the enemy's kunai and thus Kakashi's left eye is slashed to form the scar that Kakashi still has today, blinding him in the left side. Obito saw Kakashi injured, and had flashbacks of his laziness, and lame excuses about getting tardy, which made him realize how Kakashi loved him as a friend, even though he disliked Kakashi. With that anger, Obito awakened his Sharingan.
Obito's Sharingan eye only has two tomoe, implying that Kakashi succeeds in fully evolving the eye to its third stage and eventually even the Mangekyo form at a later time.
It would also appear that Kakashi's beliefs came from Obito. Obito was the one who said that those who don't care about their comrades are worse than those who don't follow the rules. Kakashi reflected on this principle during Team 7's bell test. It seems that principle is Obito's legacy to Kakashi who visits his grave before every mission, which explains his infamous habit of tardiness.
The eventual fate of Rin has yet to be revealed, but on a number of occasions Kakashi has told people in the present that the people he cared deepest for were all dead. This would seem to imply Rin loses her life at some point after the Kakashi Gaiden but before the onset of the main Naruto story. It seems as though, like Sakura and Sasuke, Rin had feelings for Kakashi that were slightly one-sided in the onset.
Also, the man who would become the 4th Hokage (Yondaime) is never referred to by name, which adds to fan speculation that he is perhaps Naruto's father.
