Okay I played the whole game like 4 times and watched youtube, but I never saw Andre?!
Andre is accompanying Shawn Greene and accidentally mistakes Lee Everett for a walker, but after learning that Lee is with a young girl, puts down his firearm. He explains to them that they are searching for their friend, Chet, who was last seen being attacked by a Walker, but is now missing. As they are discussing on where he might possibly be, an undead Chet arrives, coming around the corner, forcing Andre to draw his sidearm and tell everyone else to get to his patrol car. As they leave for his car, he can't bring himself to shoot. He runs back to his car and drives away, leaving for Hershel's Farm. He drops Lee, Shawn, and Clementine off at the farm and gives his condolences to Shawn about what had happened to Chet before driving off.
This never happened in my game? Chet just lived and helped to push a car away so he could escape a couple of zombies with Shawn, Lee and Clementine?
