I had a problem with the hurricane devastation track as there were far too many trees that had leaves and rows of telephone poles that were still standing and not bent, or broken. I know it's a minor complaint, but to me it was breaking the illusion at the beginning of the episode.
In the other hand I loved the fact that they addressed Dave's point as they made the ZombieWagon stranded in the middle of the tornado path. What I don't understand is why Al and June decided to sit in it for so long and not go out to do the survival thing, scavenging for the supplies. It is also no wonder why they're sitting on the roadside as the MRAP are notoriously fuel hungry (3.5 miles per gallon, 300 miles on 85 gallon tank).
June's and Al's rig however is made for the long range hauling. But, if there is a fuel scarcity, why they haven't added a small tank at the rear for scavaging what there is left out there. I don't believe that States would have run out of fuel at the zombie apocalypse, as they have developed oil fields and refining facilities to treat the raw product. All the survivors need to do is to learn how to maintain and operate them. They don't even need to reinvent the science or dapple with the major engineering studies.
I loved the way they introduced the theme of weakness through Al's health problem. The worst case would be the malaria infection. There is really nothing June could do to make it better as they had no supplies to treat a major sickness. But that was just a counter-point for the real introduction of 4B's main villain, The Filthy Woman. She seems to be super strong compared to any other main villains as she's travelling alone and still creating fear wherever she appears.
June showed no weakness on handling the situation after it became clear to her that the man wasn't going to listen reason. As we have seen in the TWD, there are people who don't take part into the scaveging hunts as they mainly care for other people, or do things like for example Hilltop's blacksmith does every day. Morgan shows great example by continuing the tradition of leaving a box of supplies on every visible mile-marker.
In June's situation, the fastest way to find the illucid medicine would have been learning how to pick a lock or shim it as those masterlock's they used in the ZombieWagon are notoriously easy to pick and bypass. Bashing the lock with your radio would have been the very last thing I would have personally done. Thing is, if you're so depended on the radio, why would you use it as a bashing tool, as the chances are you will break it sooner than later.
In Al's situation, the girls should have cleared that car's immediate vicinity from the dead. It was kind of obvious from the setup that they were going to use the trunk trick to kill the mud zombie. I don't know how it didn't hit the jack on first time when it crawled under the car.
It's sad that they had to abandon the ZombieWagon on roadside with all the supplies still inside. It should be included into Morgan's nomadic voyage through the wasteland full of dead. Now it belongs to the Filthy Woman.
