While Athena seems trustworthy, it remains to be seen how Cylon control works.
Once a Cylon is out of the good and up & running, CAN it completely control its thoughts and actions?
Is there, in fact, some sort of Cylon telepathy – or do they need to interface to receive new directions?
Or can certain situations trigger deep-rooted programming?
When Boomer (it was Boomer in the early episodes, right?) planted the explosives and shot Adama, was she responding to internal impulses or external instruction?
And can it happen to Athena?
I don’t know.
