Why did they even put the option to say "No" to her?
That's one of the problems I have with the games...they give you options that actually could change the course of the story, but they're just there to make the player believe he's got freedom of choice since in the end it doesn't change anything. Or you can just stay true to yourself by always choosing "No" with the hope that after a few times the NPC will give in xD Game Over
