Chandler Riggs has officially said goodbye to his role as Carl Grimes on The Walking Dead [1]. The 18-year-old actor was spotted at a Xbox Live Session in Las Vegas on Thursday sporting a short haircut that made us all do a double take. The transformation is a huge departure from the signature locks he's sported [2] on the hit AMC series since 2010. Chandler is set to exit the show [3] when The Walking Dead [4] returns on Feb. 25. Until then, check out all the clues we have about how Carl's impending death will play out [5] on screen. Gone too soon, Carl. Gone too soon.
