But isn't his birthday supposed to be after midnight or the next day when Obitto said that so if it's rising sun that means that it's already his birthday ? Either way it would be good for Sakura to find out about it and give him a big juicy present
Kushina has already done that there is no reason to do it again , if anything is gonna appear in Naruto's subconscious its either gonna be Jiraiya or the SO6P and i think its gonna be the later it does have a lot of foreshadowing
I don't see the SO6P cause most of naruto's flashbacks are people he's already met and interacted with. He has never seen the SO6P but Jiraiya is a great possibility cause he left with no closure at all.
