Yeah, one of the conversations with Cullen in his office has him mention that Meredith tried to nurture his mistrust of mages after what happened in Ferelden, hoping that she could mold him into her image as a similar authoritarian Templar.
Actually gives a newfound insight to why Cullen's stance on mages swung back and forth a lot in DA2, that unbeknowst to us, he was attempting to reconcile the tough-but-fair stance he and the Ferelden Templars had, with the hardliner stance that Meredith and many in the Gallows held.
Maybe some will think it was due to him being badly characterised in DA2 (and many decried him about it), but I like to think that it's because he's just a hero of another story that Hawke was just casually wandering into from time to time, so s/he never got the whole picture.
Ironically, that's pretty much what I'm working on right now, though Hawke's a little more than once in a while. I'm a sucker for the couple, but it's all Cullen's point of view so it's dealing with Meredith, trying to navigate what the letter of the law tells him, and the spirit of the law tells him.
I honestly wish they had given him more time in DA2. He's kind of like (God help me I'm about to sound like a REAL nerd here) Harley Quinn. Harley was supposed to be a one shot sidekick for Joker in Batman the Animated Series, but she became so popular, and was just beloved by the creators they kept bringing her back, and then DC dropped her into the comic universe.
Another example is Phil Coulson.
In a way, it's the same with Cullen. Went from just throwaway to well, having "ites"

Of course there's a great deal I wish they could have done more with in DA2. The thing had so much potential.
Yeah, I felt the same when Wynne mentioned that she used to be a bit of a cougar and drunkenly revealing that Rhys' father was a Templar. Between that and Loghain doing the Dark Ritual with Morrigan, those are some serious mental images I could have done without.
Not that I think they're unattractive or anything to do with their age, just that when your character isn't the one in that romance, it does end up being like finding out that your favourite uncle has been screwing a teacher you had a crush on in school.

Yeah, pretty much that. Something to be avoided at all cost and if needed scrubbed from memory.
I forgot about Wynne's TMI. I do remember Alistair getting all creeped out about the idea of Wynne having a sex life.
And even when Loghain was in Stolen Throne, I didn't want to think about him having sex. I really loathed his character.
Oh and how can we forget Morrigan's litany about Flemeth and the men she took for "company".
