Oh wow, that's a huge addition in that case, an entirely new camp character basically! Makes me wonder how much additional things are added in other Origin companion playthroughs.
It varies. I would have to check but I feel Gale has several big things but not too much dialogue variation thrown in throughout the game (I am slow, it always takes me a few months to finish a playthrough), while Shadowheart has her wound and the Cleric of Shar tag, Astarion has his own variation of bite-night (which is when the Cazador scene happens) and they all get their little scenes to reveal their secret to one of the gang. I feel for Avatar-Astarion and Gale someone went out of their way here, because in all the variations of the vampire reveal there are just so many ways to piss Gale off through trying (and failing) to play dumb or be obnoxious. Astarion has a lot of small things along the way too, for example Granny recognises him as undead and he can offer Wyll to be his attorney because he was a magistrate once ... 200 years ago ... possibly corrupt. XD Honestly I love this option because it is so chaotic and at the same time makes Wyll's lack choice in the end more palatable. Companion-Gale has personalised variations for each Origin of how they would picture harmony during his magic lesson and a way to compare them to Tara during his party dialogue, and also pretty deep epilogue variations for Origins who romanced him, not just for Origin-Karlach.
When you play as an Origin like Gale, do you get to do his own romance scenes with your chosen romance partner as well as theirs? Or do you only get to see those when you're playing as someone else romancing him?
You always get the romance of the character you are romancing. Avatar-Karlach seems to have gotten a lot of attention here. She has her own variation of Astarion's act 1 scene and some special first kiss scene with him in act 2 - and the most spectacular break up with Ascended Astarion. She can also be accompanied by her romance (but Halsin) to Avernus.
Of course this is tricky in so far as a lot of character development for each character is hidden in their romance scenes and you have to get those plot-beats elsewhere, when you play the character. I romanced Astarion and Gale with each other because their romances deal essentially with the same themes and their key moments roughly align, which was great. Absolutely loved it. With Avatar-Shart I romanced Lae'zel and while I thought Bae'zel and her romance are great, it didn't work so well for Shadowheart's story - at least not for me. I'll start that again and probably go for Karlach instead (or maybe Gale, but I was pretty happy with him as a best friend character, he's such a good friend to her)
Unfortunately, I am out of time, so the rest of my reply will have to wait until later. Great day to you all.
