Much better episode. We learned Mexico border is blocked, and that the entire west coast plus everything east to at least Colorado has had the major cities Napalmed.
At least at this point I don't know if we will ever know the origins of the disease. The theory that mother nature is protecting itself is one I had always thought about and reminds me of the movie The Happening with Marky Mark.
Again, better episode but still needs to get better for me to continue watching. I really don't like the characters at the moment.
