This flashback episode spread some light into the characters past which was insightful. We see Jake trying to apply for a job as a pilot but not getting it as he has worked for a dodgy company that he can't tell them about. We find out that the company is Ravenwood - the dodgy clan who tried to invade Jericho and steel all their supplies. We see how he makes his way back home to Jericho.
We see Hawkins and how he knew about the bombs and kidnapped his family to keep them safe in Jericho. We see that in Hawkins removal van he has a big bomb. We also see how he was involved with a female rogue agent who was kidnapped by some Balaclava cladded baddies - the baddies tell Hawkins he has to deliver the bomb or they will Kill her. So we are left wondering did he deliver the bomb, what happened to the girl......
At the end we go back to 8 weeks after the Bombs and back to Roger and the Zombies returning to the town. The last scene was a cliffhanger as amongst the zombies we see the female agent that Hawkins knew.
Good to have Jericho back - I love this program
