I purchased the walkthrough but I still don't know how to unlock the fourth CG on page 3 of the gallery, I need more guidance and who is it about?I only have this last CG no unlocked

I can't find all of the endings. I have the Mary, Nikki, and Erin ending as well as the secret agent ending. What's left besides Stacy? If it's possible.

So I'm going on a date with Mary and she's talking as if Stacey told her where we're going and to,d me something about Mary's past. OK, except that never actually happened, even I didn't know where we were going until I picked up Mary to take her. Bit lame.......

When you're at the point in the game where Nikki has just asked you to meet her and Erin at the cafe, and you can shower/workout, if you click on Freddie in the contacts list, it goes straight to the scene at the cafe. Oh, and when you're playing the volleyball minigame, you're being asked for every shot if you wanna disable the tutorial in future playthroughs. If you choose no the first time, it shouldn't come up again the next four shots....

I've done all the routes I can figure out, but am still missing the last 2 CGs on Page 3 of the Gallery. Anyone know how to get them?
