My husband has disappeared twice on me already. So does it worry me? Yes, yes it does... and I know how painful it will be when we're parted again. And how painful having someone you care about having no idea what you've been through together. [Although he's not talking about Itachi in this case.] But I guess it comes down to this. We could be taken away from or made strangers to each other unexpectedly in a heatbeat no matter where we were.

[There was a girl named Sugar that Law knew (how well... who knows) when he was young. A Devil Fruit user, like himself, with the power to turn people into toys. And once they were turned, all memories of their existance were erased from everyone around them, leaving the toy as the sole person to know of what once was.

They could become strangers through injury or jutsu or so many things...]

... oh, I know. It's not for everyone. It's really not.
