I feel like as they live together she might slowly start to like him just because he's strange but not a bad person. Though when that does happen she wouldn't admit it lol.

I'm enjoying that she doesn't want to tell him who she is. Though we will see how long that lasts with her ego.

If/when the camera shenanigans happen, most of the pictures would probably be taken without Sephiroth actually knowing about them. Or he would know a moment to late. I don't imagine her asking for permission but those details can be figured out when she has the camera. If you don't want anything crazy she can always get caught and then cashed away.
