13. The Pristine Prison Grass
Look, I'm trying my best not to be picky, but there's something up with the Prison yard's grass. Namely, it's pretty damn pristine. Ok, so perhaps it's not good enough to play bowls off, but it still looks in pretty good condition for a place which hasn't seen a gardener in a large number of months. Let's try and think about this logically the group encounter the prisoners in the season 3 opener, and in the next episode (Sick) Axel lets slip that he and his cafeteria-bound friends have been locked in the cafeteria for 9-and-a-half months/294 days. Yet it's unlikely that the guards would've just shut them in the cafeteria on the first night of the apocalypse, so we should probably throw another month or so in there to account for all the violence, fighting and disease-spreading which led to the fall of regular civilisation. That means the grass has been growing for 10 months. Yet it sure as hell doesn't look like it does perhaps it could do with a slight mowing, but things don't look anywhere near as overgrown as they should be.
