So exclude Lae'zel, exclude Shadowheart - who's left for romance when you're playing a honorable character? Only Karlach, whose good ending is sacrificed for the sake of a cheap tearjerker.
All of them - except Minth and Ascended Astarion probably - but what's the problem with Karlach? That you have to join her in Avernus? That's is not looking terribly favourable on your stance on loyalty.
