I think it should be obvious that the zombies are organised when the pin stripe/ink/"paul"/the one with markings is about, and it would appear that he is commanding them - both convoy ambushes/attack on the towers. I don't think it's too far of a stretch to say that he has the ability to order the other kinds about too. I believe that they will follow orders from him, whether this order is to take someone alive, attack where it tells them to, or in the case of the big ones, don't eat the other zombies. I'm thinking this could be either a military type order, or as previosuly referenced in the story, an insect-like system.

What seems odd is the difference between the experiences of the tower, skittles and the colony. Members of the tower/mallers know about the zombies being capable of being organised. Whereas it would appear skittles hasn't. From what we've heard, his experiences are of the different kinds in the wild, in small packs or alone. He thought the jumpers were gone, but we've only seen them during an organised attack on the tower. On the other hand, the colony hasn't even seen any different kinds or an organised attack. It's strange because I'd imagine that after the initial wave of biters, the different kinds would come out too.

After some thinking, I'm putting forward my theory. So the zombies are at a hospital, and one particular zombie that is injured that we know of has an arrow in its eye. It is possible that one of the big ones is the same one. As well as the fact that there are some char-grilled zombies walking round, maybe they need some fixing. Crazy idea, but when a couple of points lead to something, I'm sticking a flag in it.

Considering we have gone 5 episodes without hearing from Lizzy, I reckon it's highly likely that she hasn't been conscious for most of the time between the explosion and now. I know that the story telling doesnt always keep to chronology, but I think that this makes it very likely that she will have been captured by the zombies. If we do go back to seeing the story from Lizzys point of view, then I think it would probably be as her waking up being held as a prisoner or being dragged along by the zombies.

Just had another thought. What if the zombies are wanting to use human body parts as repairs. Brings a new meaning to the phrase, "an eye for an eye".

Anyone think its sad that Saul and Lizzy weren't there to witness Burt talking about his buddha belly.

@nikvoodoo sorry about the wall of text, I think i got a bit excited lol. But at least I don't get classed as a 'kid'
