Note to fugitives in a post apocalyptic world: Don't kills vicious dogs. Their owners will be vicious in return, capiche? Unfortunately for Charlie, Miles and Nora (who reunite with Aaron and Maggie this evening), they do exactly that, and land themselves in a whole lot of hot water. So much for searching for Danny eh lads? Speaking of Charlie's little brother, he's got the chance to escape his underground bunker while his mammy is forced to reveal information about Ben's role in the blackout.
