10 Battlestar Galactica Twists You Never Saw Coming

Yes, the very end of the mini-series saw the four Cylon models that have been so far exposed gathering at Ragnar station. Number 6 seems to function as a leader for them, with Aaron Doral and Leoben Conoy having been exposed by Gaius Baltar and Commander William Adama respectively. Then, as the three of them discuss their next step with the copies of themselves, a copy of Sharon 'Boomer' Valerii joins them.

While this particular model would later go on to become Sharon 'Athena' Agathon, the reveal that one of the core pilots we were rooting for was a Cylon was a final twist of the knife by the mini-series. Already a lot of changes had been made to the ethnicities and genders of the named characters we were looking for (Katee Sackhoff replacing beloved 80's TV star Dirk Benedict was something of a protest-point), but making Boomer a Cylon?

Was this going too far? Was it a twist too many? As it turns out no, this revelation allowed for a more detailed understanding of what it is to be a human-Cylon. But nobody saw it coming when we were first watching the show.
