Unlike other members of the Uchiha line, Shinobu wasn't born incredibly talented in the fields of ninjutsu or possess a high level of intellect and didn't become so until much later in life. Shinobu Uchiha was the son of Inabi Uchiha and his unnamed wife. He enrolled in the Leaf Village Ninja Academy at the age of eleven and struggled the entire way through, being held back two years in a row until he finally graduated at the age of thirteen. The sight of the Sharingan hadn't frightened Jun or put him in a moment of hesitation. It had solidified his conviction in believing his foe a spy.
