Your uncle, Simon, who was also the lieutenant of the Taskforce, sadly got bitten by a zombie a couple of months back..and before he lost all his humanity, he broke his jaw. So well, he couldn't bite people

Now? The apocalypse had passed, and Simon was still a zombie.. Captain Price said that he had to retire due to becoming a zombie..but still he never took off his mask or millitary gear

You were on the couch, and Simon was limping around..grunting and groaning like usual
