Okay, I know Lee is dead. I get it. I'm not gonna be a denial(!)person. Also I know that I'm not the only one discovered this but, Lee's bite marks looks different. In Episode 4, if you look at the trash first, in ''No Time Left'' you'll see bite wound looks like scratch. If you pick the walkie talkie first, bite wound looks more like a full chomp and deadly. I'm guessing that choice is gonna be important. They could a just add walkie talkie scene not the trash one. Also one of the telltale guys said in Playing Dead episode:"You don't care about the details you just want a find Clementine."
