weird logics by the survivors
so the main casts fought to join the rest in carriage 15 , instead of leaving them there closer to the zombies they tell them to move to the front which is much safer.
Maybe there just isnt enough space at the front but why is everyone securing the entrance in the front when theres a horde of zombies at the back. It doesnt make sense that everyone is concerned about keeping the newly arrived group lock up instead of the mass of zombies at the back. Its just common sense to secure the back first which is a much bigger threat.
