Thank you!
That might well be, it is a topic I tend to jump on because it was such a good experience. ^^; But I have the impression that most folks who are fond of these two as a couple, also have a fondness for this particular scene because of how emotionally warm it is and because of how much Gale's voice actor and writing lean into the drama of it while keeping it sincere. I have heard that Minthara is good if you want to go through with ascension because she edges Astarion on, but I haven't tried it yet. Wyll - if I remember correctly - was more concerned with doing the right thing, but nothing he said was memorable enough to stick.
