My opinions also haven’t changed much between playthroughs, here are a few though:
Barth, one of Aradin’s gang with a vile temper. After I managed to resolve the situation with the locket amicably, I now think that he needs better friends, less wine, and some anger management training but ultimately, I take extra care to save his skin at the gate now.
Wulbren, what a horrible person. His diary made me think he was ok once, but prisonbreaking him and the tieflings by getting myself arrested made the difference. I still think he’s a tiny pile of spite but he makes you feel like he is a reliable person to know when you are in a pickle, so I can now understand why the gnomes follow him.
Cal & Lia, I thought they were lovely but ultimately side characters to their brother’s quest. Meeting them from inside a jail cell made me appreciate them more as characters and just made me wish they had a bit more content.
Valeria, shitey little elephant. Reading her diary didn’t change much about that opinion but it also makes me feel sorry for her. That I once forgot to free her from the temple for about a week, seems to have been a good choice in hindsight, gave her some time to dry out.
Figaro, I thought he was ok, had a bit of a squabble with his sister, but that’s siblings for you. Then I managed to kill Dolor before he made it to Facemaker’s Boutique and Figaro instantly became obnoxious. Robbing his cellar also made me discover that he forged his father’s testament and cheated his sister out of her inheritance. I feel much better robbing him now. His one saving grace is that he apparently helped Leon with his plan to save Victoria - but I assume that he didn’t do this out of the goodness of his heart either.
