Then you waisted a picture you could have used directly against Eric to make demands..

Forget turning mom against Eric. As long as he is there just focus on getting rid of him.
A later option, if you go the hacker route, will allow you to make Eric your bitch. (Or have him killed. Your choice)
Lol when i see the mother reaction, i just reload the game. So i have the photo with me. But the problem is, that i wanna do kate's mother route. I mean i wanna do sexy with alice. So the photo i do not think for me is helpful.
The real problem is, what i have to do for start the kate's mother route?
I have wallet attive, and i am at the point where aunt kira tell me to stolen his wallet. Do i need always stolen is wallet to start kate's mother routes?
Edit 1
Guys who is better wallet or Kate's mother route? I try to search in the event thread. And is it seemed to me to understand that if I follow the opportunity of the wallet, I can have Eric killed by dangerous people? Because if it were so, I'd rather let Eric die!
But I did not find anything about kate's mother. And I would like to understand which of the two gives more satisfaction. I would not want to find myself with even more submissive alice to Kate or Kate's mother or someone else (i read that Kate's mother wanna a movie. That the fear that Alice is blackmailed for the video, does not make me feel comfortable). Can someone give me some more advice / information?
