This is such an excellent episode. It answers all the questions that has us asking even more. The Mysterious Mister Smith is a excellent new character. Typhoid Mary becomes a weapon. Valhalla and the United States of **** reveals itself. Helicopters and warfare in the next episode. Its too bad this series was canceled but I guess it should have been. Most of the episode from the first season weren't the most impressive. The episodes revolving around Valhalla were excellent but the rest lacked a lot of things. Over all this was an excellent return to the series. Hopefully there are more episodes like this.
