Listened for a second time and thought about a few things:

1: Burt tells Nick that revenge doesn't end the pain... Is he a little haunted by what he did to Scratch?

2: CJ says that the zombies can live for long periods without food. Were the zombies that swam to the boat around before the outbreak and starting to starve, or do they get really thin and starved looking quickly?

3: Mind is still blown!
