"Because," Chrysalis says, slowly, like speaking to a foal, "They won't do you any good at disabling Ashtown's defenses if they aren't accepted back. Do I need to use smaller words, Rose?"

She snorts. "I believe you're crazy enough to push it. I also know that, if you do that, the world's doomed anyway and I'll be tracking you down to teach you the meaning of pain. You can't get past Ashtown's defenses without me. So really, you should be accommodating me, not the other way around."

Her eyes narrow. "If you proceed with your plan," she says, "And offer them a chance to help 'of their own free will', it will fail. And we will all die. That is the simple fact of the matter. You will have to accept that my plan is the only one that will work. If you don't, then we can all spend the next four and a half days getting very mad at each other and shooting each other on sight."
