no no no… listen up. (spoliers)
she says the following… (paraphrased)
"as i said, i’ve allowed you to keep your life for two reasons. and the second reason is… i want you to tell him, face to face, what happened here tonight. i want you to tell him all the information you just told me. i want him to know what i know. (where all of the remaining people live and she’s coming to hunt them down) i want him to know i want him to know (she wants him to know that she knows where they all live). and i want them all to know, they’ll soon be as dead as o-ren."
then he’s like… ok she knows all that… but…
"does she know her daughter is still alive?"
and the answer is, no, she doesn’t.
