To me it just seems like another one of Dorian's curiosity-driven questions that he asks to satisfy his own intellect. To me his tone in the question itself doesn't imply that he was even thinking about anything untoward.
I didn't think he was actually planning to do something, sorry if I wasn't clear about that. More like ... even as just an intellectual exercise, some things cross a line because you begin to lose sight of the fact that there's a sentient being (be it human or spirit) in front of you and not a puzzle to work out. The unfortunate "mages are used to viewing spirits as tools, not caring or even knowing how many spirits are hurt by that" dynamic would only add to the risk. I think this is an example of the questions that "can be shackles", as more-spirit-Cole says.
However, I will say that his question to Varric about red lyrium does lean in that direction, yes, which is why Varric responds as he does to it.
Oh yes. I even remember exactly where I got that banter, it shocked me that much. Still, the fact that he is able and willing to reflect on the occasional problematic attitudes is part of why I like him. I frequently found myself wishing I could talk to him more because Cole aside, his personal journey is among the most challenging of the companions and (as usual with Bioware, sadly) many aspects of it were barely touched on. People who insist on claiming he's nothing more than some in-your-face token homosexual boggle my mind something fierce.
I have never suggested that any of the mage followers drink from the well; I've never seen any of the responses. While I highly doubt there is different dialog for a romance, I am sorely tempted to pick it the next time I reach the Well in the game since you make it sound so intriguing, just to see what he says, especially since he does have a romance-based line for not wanting the Inquisitor to drink.
I'm glad I didn't spoil it by being more explicit about what he says, then! I like humorous Dorian -- his bets and banters with Varric are awesome -- but I also really like thoughtful Dorian, and that's definitely one of the best examples.
It's bad enough with the option for Hawke to sell Fenris back into slavery, but corrupting a spirit of compassion like that? A being whose only desire is to help and heal? *disgusted noise*
Yes, I really hope Bioware will continue to stay away from that sort of sheer evil, at least in games that heavily imply a "heroic" protagonist like the Inquisitor is meant to be.
I just wanted to say this entire bit sums up perfectly how I feel about that scene! Such a let-down after how perfect his 'dinner' scene is ("...thank you for helping me find this again, you don't know what it means."
).
It's like the two scenes were written/directed by totally different people. One who really grasped the essence of what might make someone choose the more-spirit-path, and one who didn't bother trying and brushed it off as thoughtlessly as many players do.
Good to see you in here again too, btw! 
Thanks. Being among the apparent minority who really love the spirit-path can get lonely sometimes.
In regard to your point about the Nightmare demon - I think it would've had more impact if our companions had been trapped in nightmares again, like DAO. It's a lot easier to remain confident/brave when you're surrounded by friends and simply being trash-talked. A lot harder when your mind is being warped!
Indeed. I wouldn't want to be the one who has to "save" them like in Origins, though. Being a strong protagonist/leader can be satifying, but I like it just as much when my friends show their strength. Ideally, we'd all help save each other.
I thought he might view Cole as a tool or something sub-human. Instead, there was some wonderful bonding and insight there. It comes second only to Cassandra's friendship, for me.
I think Cole's sincerity and kindness can bring out the best in people, at least those who are not too jaded or prejudiced or just plain callous. Untouched by mortal preconceptions and biases, he sees and cares for you as you are. He does not see a dirty Vint or a deviant dishoring his family -- he sees Dorian. To him, Cassandra's love for silly romance novels is not a hilarious target for mockery or a contradiction of her badass duty-bound Seeker self -- it's simply a part of her that brings her joy. And so on. That is probably (more than?) a bit frightening at first, but also a rare and priceless gift for most of the companions once they allow themselves to trust him.
I like to think Varric eventually sees that he hasn't really lost Cole, especially since he's still at Wicked Grace. He might be a little more wary because of the whole Anders thing, but I doubt he'd stay that way forvever.
That is certainly what I hope and want to believe, yes. As I said, he really isn't a bad guy ... just very set in his views, moreso than Solas in a way, which is rather ironic.
I tend to see him as asexual and aromantic anyway, but pairing him with the Inquisitor feels particularly off.
Same, especially the more spirit-side of him. I desperately wish Bioware would give us the chance to connect as deeply with companions in a platonic manner and respect those friendships in the same way as a "romance". Jackhammering tab A into slot B should not be the pre-requisite nor the only way for the protagonist to have any chance at a lasting and mutually caring bond instead of the one-sided unpaid therapist thing. Especially with a character like this.
