I know that. [And she knows that she and her housemates are targets - not only because they agreed to help, but because they're friends.]

But that doesn't really mean anything. Nami and Sayo weren't doing anything when they were attacked. I wasn't doing anything when Yuber set my house on fire with me trapped inside of it. If he decides to retaliate against someone else, it will still be on his head.

[Because as far as she's concerned, Nu deserved it and more.] Hopefully the Rogues and the League will have seen Luffy's post and be more on the alert for the sake of people who can't defend themselves.
