hahaha yeah I remember that. I thought this is a good role for him to just be trevor again.
also thank you for writing in here because a question came up to me recently when I wanted to sleep. How long does the Zombie apocalypse lasts? technically for alot of Zombies it shouldn't last that long because they are caged or chained somewhere and others like the ones in the crater that mass thousands on a "small" place with no protection against the forces of weather. I guess even the zombiefied human body needs some kind of nutrition,otherwise the whole "only hunger is left in them" phrase would be simple excusion why they attack you.
So without food they should start to rot where they stand and walk at some poin of time,more and more people die which means less food. So technically it should end sometime because the human flesh rots down and the body collapses and in the end also the zombified rain stops working.
You could go so far to say if there is a zombie somewhere frozen and it would break out 50 years after it stopped and infests another human the whole shit can start from the beginning.
Did they ever mentioned what happens in Europe? I can't remember but all I know is that the whole U.S. is infested and on the run. Like the gentlemen sit there in London with their tophats and monocle,sipping their teas and laughing "This substance we created works very welll ho ho ho, cheerio mate".
