As you may remember,
Aleks Paunovic will be playing
William Adama Sr in an episode of CAPRICA ('The Dirteaters') in flashback scenes. I found this BTS photo posted on the facebook page of a talent agency. The photo was labelled as SANCTUARY but from the tattoo on Aleks' hand, it has got to be from CAPRICA. Which would make the two boys in the pic, young Sam and Joseph Adama.
I'm guessing that the boy on the left is Sam and the boy on the right is Joseph because in an interview with
SciFi Wire, Esai Morales said .... "There's one we unofficially call 'Adama-rama.' It's called 'Dirt Eaters,' and it shows the history of my brother [Sasha Roiz] and I on the show, our history when we were little, when he was actually shorter than me."
