That’s fair. I’ve also noticed dialogue in places that assumes you are not the origin character you are playing, or ignores when specific characters are not in your party.

Tap for spoiler

When you recruit Minsc as Shadowheart, there is a place in the dialogue tree where you refer to yourself in third person. There was a line suggesting I ask Lae’zel about a githyaki slate in Act 1 when I chose to kill her instead of join her earlier in the game.

I wonder if the difference is because Karlach was a later addition to the game as an origin character.
