A few thoughts on the drunk in padded cell. I'm thinking he was a slow turner, and potentially there a few people in the prison were slower turners.
We do know there was a fight in the drunk tank and people were injured. And that the drunk tank was overflowing.

It seems highly unlikely that they would mistake zombies for merely drunk and move them to other areas. And we know that he was somewhat responsive earlier in the episode.

This gives us a few things to think about:
- This is early in the story, so could the earliest turners be slow turners
- Interesting that our guys was in the padded cell, seems like the place you would thrown the one who started the fight.
- I wonder where the person who entered the prison got exposed

Long grasp theories from this
- Alcohol slows turning which is why they were so spread around the place
- As this is very early could we be looking at some of the first turners from ground zero, ie exposure to the fog turners are slow and appear drunk as it turns them. We know from WA that simple exposure to the fog doesn't turn you straight away. So maybe some critical level needs to be reached and even then it takes time.
