I too finished the game last night. My end party was a romanced Gale, unascended Astarion (also romanced, No Romance Limit mod, thank you very much) and Karlach. As Astarion ran off to the shadows the only character that commented was Halsin, and it wasn't entirely distasteful but it wasn't really full of concern for his well-being either, so now I wonder if it's random which companion comments and what they say, or if it was just bugged? This is only time I've managed to bring myself to the final point of the game so I'm not certain.

I did get a very quick scene after the docks with both Gale, then Astarion (thanks to the mod I assume). My gal was able to tell Astarion they could still remain together, perhaps in the Underdark. It felt in some small way like a tiny bit of closure, but I was still left wanting when compared to the ending with Gale.

I sat here for a good hour after the game ended, watching the credits roll, waiting for the Withers scene and thinking about my playthrough as a whole, and I just felt.. lost and loss. It was SUCH a disappointing ending overall compared to other games, and I hated that the story was over. I know I can playthrough again, and try for different outcomes, but damn. #JusticeForAstarion please. I get there are a bazillion Karlach lovers out there, and Larian in turn fixed her ending a little, but please do this for our broken broody elf. He deserves better, especially for those of us that choose not to let him ascend.
