It really looks the legacy of previous episode is that the cylon fleet backs up for a while and they have to deal with their inner crises - and it is mostly the cylon escaped from Pegasus who has been creating her own resistance and she has no plans to give up, under no circumstances. On the other main storyline is Roslin, whose death is getting near and she is having those flashbacks and in one of them, she remembers something very important and that really looks even more that next coming episodes might be the flight between Roslin and Baltar.
And Sharon and her unborn child storyline was expected too. They were going along with it too long and now it was a real danger. i most say the moment on the corridor - where Halo is stopping them.. it was good one.
