Here is something of interest I saw over at sciffy posted by Miss Echelon
Tricia was on Late Late Show last night, and a new clip was shown from upcoming BSG ep. I think it's up on Youtube.
Anyways, in the clip Six tells Tigh something along the lines 'if humans are so good, how come you killed your wife on NC?'
Tigh punches her and she punches him back. Maybe it's related to the promo pick where Tigh is taking Six out of the cell and his face looks weird.
Question that popped up for me was: How does Six know it was Tigh that killed his wife?
