I've tried not taking the 3rd picture and I still never get the camera, which means the quest never ends and you can not ever get to talk to the fortune teller again. Not game breaking no, but completely ends that entire quest chain.
As far as the Silver Slut, I have no clue. I obtained the items, went on initial fight. Then about 5 or 6 fights later, I got the message about crime (at this point it's always the group of guys firing at you), activated, tried hypno, tried tits of steel twice, then blank options. It happens every single game, sometimes after a few fights, sometimes a few weeks later, but always.
I should point out that I am playing 1.0.3.
