ok thats really not a good question. im sorry but its not. but because i have beaten the game 5 times i will answer it for you. KEEP GOING! just go where you havent been. look at your map and find out where to go. after you see the cutscene with her going on the other side of the wall go into the sewers. after that you have to get past the swinging axe type things. keep going..... im not gonna say everything that u have to pass to get to her but really just keep going and just go to unexplored areas.
