Kara working with the Cylons, after what the Hybrid told her...just seems a bit of a stretch to me.  Adama's going to implode when they show up with a busted-up base ship saying "hey, we're allies now!".  Um, sure...  Roslin leaves a Cylon in charge of the Colonial government...unknowingly, of course...it'll be interesting to see if what Tori decides about working together with the Cylons...Tigh will have to make a decision too.  The Chief?  Dunno yet...we didn't see him this week.
I didn't realize it was Nana Visitor until nearly the end of that storyline.  Wow, time hasn't been too kind to her...  I agree, trying to get the De'annas unboxed was part of what started the civil war...the Cavils won't change their minds on that point, so a bluff or ploy of somekind is going to be needed to get access to unboxing them.  From the previews, I don't see Boomer changing her mind...she decided who/what she wants to be.
