Any doubts i had about Jericho's return were quickly dismissed as this episode was better than half of the episodes in season 1. Making the episode start almost as soon as season 1 finished was a great touch, it didnt give the need for a huge "previously on jericho" spot and lame flashbacks. What i hope happens in this season is carry on what this episode brought, meaning concentrate on the core characters and adding a few interesting new ones and let the story run from there. I think the character Major Beck is a great addition to the show, he grounds the show almost with his authoritarian presence (and he actually seems like a good guy with any mystery surrounding him)
Hopefully Jericho will continue like this episode and maybe even get a third season.
