When Loghain becomes a grey warden his perspective completely changes. He admits that what he did was wrong and it sucks that you can't keep both him and Allistair ( although I think you can if you harden Alistair)
With Anora, when you talk to her in Awakening, it does seem like she actually like Cousland, as she doesn't act like a total B, like she does with Alistair. And Loghain actually talks about "producing heirs" IIRC. I can't remember the exact convo as it has been a few years since I did that playthrough.
Huh. The more you know! I always thought that no matter what, if you wanted Loghain alive then Alistair would leave... just investigated, and the only way you can have both is if you harden Alistair and have him marry Anora. Instead of killing Loghain, "Anora's love for her father will stay Alistair's hand."
Interesting!!
Now we're even since it's because of you I found out about Morrigan's mirror!
