Can you trust a Cylon? : Battlestar Galactica Season 2

"Battlestar Galactica" Season 2 remains totally entertaining, incredibly smart in its script, well acted, and a surprisingly funny (how can you not laugh at the scenes of Gaius and his Cylon paramour, Number Six?) - not perfect, still kind of cheesy and over the top melodrama at times, but very different from most other long TV series in this key way: you have a sense throughout that the creators (like the characters?) have a real destination or destiny in mind, that they know exactly where the story line is heading and how to get there, and they move us artfully along the way. The major theme of Season 2 is the evolving relation between humans and Cylons, the human-created machines built as robot servants who have rebelled against humans, begun the Cylon war, wiped out the "12 Colonies," and, most important, have created clones that look exactly like humans. Season 2 focuses on the clone of one of the Galactica pilots, Sharon/Boomer - the crew knows she's a Cylon, they imprison her, but she says she loves one of the pilots, is carrying his child, and gives valuable information to the crew about the Cylon enemies. But can they trust her? Or is she programmed to win their trust and then betray? If so, does she even know that? Moreover, the question is how to treat her - and we see a sharp contrast at the end of the season when Battlestar Pegasus arrives, the counterpart to Galactica, where the Cylon prisoner is terribly abused and the crew is sexist and the Admiral is a martinet. The current political analogies (Iraqi prisoners) are obvious, and it's obvious where our sympathies should lie, but is the Galactica crew making stupid decisions based on sentiment or the right decisions based on both good ethics and good tactics? Can they really gain useful information from the "friendly" Cylon, or are they being led into a trap?
