Yeah, that's when I started getting upset with the game. Walter's torch goes out and he just spazzes out. He freaks out and gets scared which makes him an easier target for the Crawler. And if he was so scared why wasn't he sticking to you being the hero like glue. Did he not believe you could protect him? It's a game but you should have never been forced to leave him. The other thing I was most upset with was the final fight. Fine, the Crawler uses Walter because he is afraid, old, and your father figure. But why couldn't you seperate the Crawler from Walter without killing him. I sooooo wanted to fight the Crawler one on one in its natural form. Even if Walter had to die in the process of the Crawler leaving him it would have been better. If the Crawler had made Walter mortally wound himself to upset you and leave his body at the same time it would leave Walter out of the way and give you all the ammunition you needed to rip the Crawler apart. When I beat the game, I was just thinking, wow that was BS.
