Here is an idea:
Could we see Six lose her baby and then go bezerk somehow so that the ramifications in the Opera House play out whereby she feels he need to take Hera as a substitute for the loss of her own child. and Baltar would have to be the one to rescue Hera?
I am stating this in the most simplified description because i haven’t exactly played the scenario out in a logical fashion yet but it seems that the tranquility of Six’s upcoming pregnancy should have some consequences whereby she will become a darker character again.
This would also tie in to the scene in the miniseries where she snaps the baby’s neck on Caprica, which may have this symbolic connection, beyond showing the fragility of humanity, and to losing a child.
Any thoughts?
