Ok, good episode tonight. The two sons had to go to another town to get medicine for the Mayor who was dying. When they arrived at the other town it was deserted except a gunman and a doctor at the hospital. The town was vacated by FEMA by some govorment hired mercenaries since our troops were fighting in other countries. They manage to get back to Jericho with the medicine and a doctor after a confrontation with these govorment mercenaries who killed all the weak in the other town.
Our other stranger was interrogated in his home by the mayors rival and his home was searched finding an FBI badge.
About the mayors son "Jake" we find out that he has been in Iraq as some kind of corporate transport in the green zone.
One of the sons left his jacket behind in the other town when getting medicine and the mercenaries have found it. Looks like they will be heading to Jericho next.
This weeks episode was good and they may have a good follow up next week as the town prepares to take on the mercenaries.
