The same Centurions who were used by Cavil and his group as slaves and who fought side-by-side with Lee and the other colonials in rescuing Hera ( which was a pretty cool site by the way). I agree with you.
Since the Final episode I’m been wondering what could have become of those (liberated) Centurions in there Base Star after 150,000 years.
By the way, how many groups of colonials were spread across our Earth?
Is it possible that it could have been (12) to represent the original colonies/ planets?
