They have comments if he does ascend, if he doesn't and during the moment, when he carves the runes.
I thought Ulma is pretty ok after ascension. They are monster hunters after all and you just created an uber-vampire after agreeing to work with them before. So from a narrative point of view, it's understandable that they are treated more as opponents than as potential allies if you go the ritual route.
In Rivington they are all pretty decent, as soon as they realised that Astarion had free will, they treated him like a person. Having had Wyll and Astarion on my team recently, I'd say they are more accepting & less judgemental than the monster hunter who is part of your group. Perception might vary but I thought the Gur are pretty well written overall and I do enjoy them as NPC, Gandrel most of all. He never dies except for science.
I totally agree, the Gur are very well written, especially Uma and Gandrel. He never dies in my games either. And yes, their reaction after Astarions ascension is pretty understandable: First he kidnapped their children and then he uses their life force and sells their souls to ascend. I would take that pretty harsh too. And as much as I like Wyll, but I have to agree, that the Gur handle the idea of treating a vampire spawn like a person better - though Wyll potentially witnesses a lot of Astarions earlier, more brattier behaviour, so he might just retaliate a bit. I want to strangle Astarion through most of act 1 ( and actually did a few times in early access, since there weren't really consequences for later story). But generally yeah, the Gur handle it pretty well overall.
