Hi, I simply must ask – how did you come to the conclusion that Sarah had a mental or cognitive disability? To tell the truth that never even entered my mind. And secondly, I think the fact that Sarah could not survive is a plus – in that it shows that they didn’t feel ‘sorry for her’ and let her live JUST BECAUSE she was somehow mentally challenged (if she was, that is). She was treated just as everyone else was treated, i.e they all/or almost all, died.
Realistically, in such a difficult and rough reality as that presented in ‘The Walking Dead’ it would be terribly difficult for highly intelligent, highly strong people to survive, so obviously the survival rate of someone with less physical and/or mental advantages would be much less. I, for one, find the continuing survival of Clementine herself to be deeply unrealistic. Sure she’s a smart kid and she knows how to shoot a gun, but really, the decisions given to her to make by the rest of the group are simply ludicruous. They never expected Duck, Kennet’s son, to face such decisions or crawl/slither/climb/run into such danger did they? So why burden a young girl like Clementine with going into almost death-like situations, when strong adults loiter about doing god knows what instead?
And that is why Sarah’s death (whether or not she has a disability) is a very realistic fatality and one which totally fits in with the rest of the story. It is a cruel world, a dangerous world, a nightmarish world. People die and become flesh eating zombies, even nice ones like Leah. If Sarah had remained alive, that would not only defy the forces of ‘reality’ such as it is, but would be preferential treatment, she would only be spared because she is ‘different’ and THAT would be unfair to people like Sarah! People with disability and others without disability should be treated in the same way, both when it comes to the good and the bad stuff.
