Cortana Quotes from halo 3

I absolutely believe you in the fact that cortana said chief leave me. She is probably delarious. In the halo 3 announcement trailer, you could even hear her scream right before her first appearence...--Halo3


When did Cortana say "leave me"?. She said something more like this: MC" Dont worry I'll get you" Cortana "Dont make a girl a promise you cant keep" --Will 16:07, 6 January 2007 (UTC)

You guys... During the last portion of the level High Charity one of the lines Cortana says while she's watching you fend off the flood attack is 'Chief, Leave me.' Which is what she says in this. She isn't actually there, he was knocked unconscious and is remembering her say that. CaptainAdamGraves 23:34, 8 January 2007 (UTC)

Well, I agree with that, but Bungie is doing an awful job if they were trying to do this effect to make us feel that Cortana's word is haunting the Chief--Master Chief Petty Officer 05:07, 9 January 2007 (UTC)

You didn't realize it was actually talking about Halo 3, didn't you, when you first saw the two kids you are not really thinking things relating the Halo 3?
