It may not even be the wrong choice. I've found that you can get different pics going through episodes again. For instance, replaying the first episode, if you tell Lilith to run when the alarm goes off (and then reassure her you know what you're doing) instead of telling her to disarm the alarm, you get a different pic. It's not of her, but it's still something you don't get by telling her to do the "I can do everything" thing and disarm the alarm.
