The craziest thing about the Carley/Doug choice? I chose Carley... because I was hoping that, with her gun, she could help save Doug. Seriously. Oh, of course I knew it was an obvious "save one person" type of a choice, but the game somehow made me believe that I could save both of them.
Also: even though I've been with the game since the beginning, I've only just now read this article - fresh from Episode 3. Man, the stuff the guys allude to in the text is just crazy.
