Okay first i want to know if the 10th episode of season 4 called Revelations, is the last episode of season 4??
Also what happen before this show takes place, how did they lose Earth in the first place, what exactly happened on Caperica? does the older battlestar galactica(1978 tell you all of this, does the newer battlestar galactica(2003) take off where the older one left off??
