The scene with Dorian's father is disturbing. I feel like I'm standing there awkwardly while younger David Gaider has an argument with his dad. IIRC he said that storyline served to purge inner demons or something along those lines.
It is supposed to be disturbing. Or well, if not "disturbing" (which is a strong word) it's certainly supposed to be evocative. Mission accomplished.
During that particular scene I like the fact that I can be supportive, even as my gal Inquisitor who has Dorian as her BFF. As an example, I usually tell Dorian "Don't leave it this way," because I know that Dorian loves his father, and just leaving with an FU to dad, while satisfying in the moment, would ultimately not make him happy. Indeed, Dorian isn't happy either way, but as he says of the conversation, "It's something."
Dorian SO needs a hug there. More hugs in Dragon Age. Wtf we get to hug Varric once if Hawke dies, and there is another one for the Cullenmancers, and that's all?
[edit]
The reason that quest chain, and also the romance, is so powerful to me is that you get to see his whole facade melt away, and that just makes me love him even more. That is the depth I see when I look at Dorian. He is in a lot of pain, afraid of rejection, convinced that he deserves it on some level, and uses his vanity, elitism, and snark to hide all of that.
The very best scene in the entire romance for me is when, on asking what the Inquisitor wants and receiving the answer of "I want more than just fun," Dorian is speechless. He doesn't have a thing to say in that moment, and it is wonderful.
This scene is even better if you go the no-sex route, and I'd argue probably more meaningful to Dorian, because of the way m/m sex is viewed in Tevinter. And then suddenly there is this man telling him that he wants a relationship without even having had sex, and he is just stunned into silence.
