I think the mistress thing probably varies. IRL I would never do it (I can barely fathom having a relationship with someone who is legally separated from their spouse, and I don't consider that to be cheating) but the game is different.
Absolutely. I only consider it a viable happy ending because in the setting, political marriages were known and accepted, even expected. It's a matter of note in the HN origin that your father plans to let you go your own way.
I think someone mentioned that it goes against Alistair's grain. This is true and something I have thought of. However, hardened Alistair is a bit more sexually liberated. I had to play the Isabela threesome scenario once just to see his reactions, even though... ewww.

This is one of the times when you can see that Alistair is not a choir boy at heart. His first inclination when Isabela asks to "borrow" him is "whatever, duty calls, blah blah." She then paints a picture for him and he just lifts an eyebrow and repeats her come-on line (if the Warden says that she doesn't own him and Isabela should ask him herself). IOW, he's thinking it over and not finding it a bad idea.
So, whatever, make of this what you will. If you prefer keeping Alistair on the straight and narrow, I imagine that is just where he would stay. But he
is open to other possibilities.
