Well, the explanation came some episodes back, and they had to network the computers back then to survive, so I'll have to let them off on that one.
Adama actually had to trust Sharon in this. I'm not sure that I could, but there really wasn't much choice between three options - do nothing and die, jump and die, or have her try to remove the virus - She actually saved the whole fleet today - yet they still put her back in the cell.
On the new Viper, I'm not so sure. I'm quite sure that the Chief has the technical ability, the patience and skill, but does he really have the right tools and materials to make it. I would have thought such a thing could only be made to precise measurements in a factory setting, with specialist metal alloys and ceramics, not by hand with a welding torch, some old junked engines and what looked like chair legs for the chasis.
I almost laughed when Tigh took the bottle of still spirit.
Good to see everyone getting dispirited eventually, but would they all do it at the same time? What changed this week?
