Minthara, a companion who could previously only be recruited by joining her side and more or less committing genocide on a grove full of tieflings, can now simply be knocked out and talked to at a later point in the game where all of that drama can be ignored.

Minthara was being mind-controlled. When she's free, she's still evil but not that evil - she even asks the player character what his excuse for killing the tieflings is, since he wasn't mind-controlled.

(Knocking her out still doesn't make sense, but mostly because at that point in the game the player has no in-character reason to think that she's special aside from the fact that all the other enemies are goblins and she's a ~~Forgotten Realms BDSM sex symbol~~ drow.)
