Battlestar Galactica 4.10 'Sine Qua Non' (open spoilers)

My WAG is that it is Roslin. The dying leader leading them to Earth, the 5th Cylon can lead them to earth. It explains how she can share Visions with the Cylons (or any Visions for that matter) without having to bring God/gods into it.

How did I miss that Tighe and 6 had sex? Was that implied on camera? I always saw 6 turn into his wife and he seem tempted then pull back in horror - I would too - that was creepy and well done 2-3 times. Tighe didn’t deny that they had sex but I was as shocked as Adama.

I think the 5 must be different right? Because Tighe must have aged if he has known Adama since back in the day, and it seems likely that the others have too (but I guess it doesn’t necessarily have to be so for them)
