The real problem here, of course, is that defeating the Pegasus in ship-to-ship action is pyrrhic at best. It's the kind of fight where even if you win, it's really a victory for the Cylons.
Curious, the only way to win is not to play.
They'll have to back down. My bet is Starbuck will provide a 'Blackbird ex machina' sitbrief as the two capital ships are at the very brink of annihilation. She'll pop back out of hyperspace, see the fight, and broadcast her 'shocking' findings. There will be a couple of Vipers lost in battle, just enough to ensure REALLY POOR RELATIONS between the ships and paving the way for the Pegasus, under the command of a confused and angry Admiral Cain, to sacrifice itself to protect the fleet after a few episodes. The docureporter will help ensure that there is extensive coverage of the rapes and force the Pegasus crew to deal with an external reality, since they haven't had anyone outside to reflect their actions back at them like a societal mirror. People in confined places do strange things without even realizing it.
