I am not sure if the writers thought out the rules about zombie behaviour.
What is a zombie doing sitting in the toilet with his ankles around his pants?
This is exactly what Amar encounters as he and Jo go to a supermarket to get some food and provisions. It is a place where Jo once worked in.
Of course it is never that easy, there are zombies behind a barricade. Jo encounters an ex colleague Chloe who is infatuated with Jo's online life until Kat betrays a secret out of a fit of jealousy.
At least we found out about a possible cause of the zombie virus. It was short on laughs and I felt the writers were struggling here.
