No idea, I've played up to day 12 and then did that day multiple times and she's only popped up twice.
If you're looking to get the videos of her, go to the night club. On the later days, Nile and her will often visit you. Just be prepared, it took a number of days before the difficulty got high enough for them to start moving out of the waiting room.
thanks, i've been wanting to see what her Game Over scene is but I only had her glitch in when I got caught one time by accident lol
