This is the third time that I've heard this story, and it's the same thing. No part 2, and I think Itachi should've given Mikoto an option. To either die with her clan or abandon them and raise Naruto on her own. Because it's her and her husband fault that kushina died that day.
@bosszombie29 Mikoto confesses that she and her husband gave away kushina location of her giving birth to Naruto. And that's how the masked man knew jowls to get the nine tails.
I wish all fanfic’s start like this getting straight to the point with what we all came for instead of most fanfics starting with boring useless background story
