The prelude to Season 4.5 continues over at scifi.com with a couple of sneak previews.  Part 1 shows a short scene between Admiral Adama, Colonel Tigh, and a couple of bottles of Ambrosia.  It's only about 45 seconds in duration so there's no sense in me summarizing beyond that but it's definitely worth watching.  It's no surprise that scifi.com is into the brief clips.  With the webisodes getting shorter and shorter it's a bit of a surprise that Part 2, featuring Admiral Adama and Tom Zarek, clocks in a few seconds longer.  It's probably not significant although it was certainly a pleasant surprise.   Please watch responsibly.
