The show Jericho (just like Lost and 24) makes the assumption that the viewer can hold a plot line for more than one episode. This combined with such a sweeping apocolyptic theme makes the show more than interesting, but entertaining and addictive.
This episode shows more into Hawkins background and crosses paths with Jake (who Hawkins researches and finds out information on Jake). The series continues to get stronger each episode and gives us a glimpse into post-apocalyptic America.
((it also reminds me alot of the book \"Alas, Babylon\" but that is a different issue))
