I don't know how many people have realised this but here we go:
In EP4, Lee and Kenny go down an empty road on the way to the docks to find a boat. Even in EP4 we see the same sign that Lee or Christa and Omid climb over in EP5. The same road that has the sign, also has The Marsh House in. Now think about this. Why didn't Lee and Kenny see this in EP4 on the way to the docks? It makes no sense. In EP5 when the 'road' has millions of zombies in, you can see the Marsh House easily, but in EP4 it's not even there?!?!?!?
Did anyone else notice this?
