Lol you people are whinning over a fucking fairy tale its a manga its not that serious. The plot sucks we get it every week the same clowns come in and talk about how this doesn't make sense and how that is a plot hole.
We get it, it doesn't make sense now stfu and post about something else that's actually related to the topic. Whinning and complaining isn't going to change kishimoto's flow of the story when it's good it's good an when it's bad it's pathetic, deal with it
Back on topic;
I hope this flashback isn't to long.
