Plucking Lemons from the Tree
Hatake apparently are an endangered species, and Konoha is not helping that.
Plus, mom asked her to get under the Protection of the Hatakes. Which they can't give in this depressed state.
Well. No choice but to kidnap them away from this dump and to a place where they can thrive and actually take care of her like mom wanted, you know. Little five-years old Kakashi is the best bet to start with. The dad should follow after, even if he's stupidly depressed. Sakumo looks like a good dad. He'll come and retrieve his son.
Raiden just has to be far enough from the shit dump that is Konoha by then.
And four years-old's legs don't run that fast. Nor five years old's. They will have to be crafty.
At least little Kakashi doesn't look to put out by his abduction at the hands of a younger child. He's being a model hostage!
