I admit that by the end of Killer Within I had tears in my eyes. This has to be one of the best episodes of Walking Dead since so much emotion was involved as well as IronE Singleton (T-Dog) and Sarah Wayne Callies' (Lori Grimes) acting was fantastic. It's a shame two great characters were killed off as they had big parts, though I think T-Dog deserved to have a storyline for himself. You'd have to admire Carl shooting his own mum, I'd never be able to do that. Chandler Riggs (Carl) is excellent the way he is able to put so much emotion into his acting. I cannot wait to see the next episode!
