I just saw the complete "bonus scene" for "The Woman King" from the official BSG website.

It gives a critical piece of information and is not really "optional" if you want to keep understanding the series. They should have included it IN FULL in the televised episode. I won't give it away so you gotta go to the website and see it.
And regarding "inner Baltar" and "inner Six", I saw an interview with James Callas (Baltar) where he said the actors still don't know who or what the "imaginary" characters are - which obviously makes them difficult to play. He says he plays "inner Baltar" as a pre-invasion version of Baltar - before he became overwhelmed with guilt and self-doubt.
