Even though it doesn't entirely clear up the mystery of the bombings, it gives just enough to know it was some sort of 'home-grown' terrorism. Whether the government/president knew about it or not is still up in the air.
It's also nice to find out a little more background info on Jake, what he was up to after he left Jericho and how he knows about Ravenwood (and what kind of people they were)
This episode actually does shed light on the series, which I have been enjoying more and more as the season progresses. I hope before the end of the season the truth behind the bombings is revealed.
