I personally didn't like Karlach story overall , bland story, and just not hitting the mark with the character writing..like other companion stories did.. I feel she is too nice and goofy for someone that killed thousands of devils in the Blood War.. During the gameplay I hoped we would visit Avernus or Elturel since it has a huge demonic presence and progress her story there. Larian decided no. Maybe a DLC is cooking, I hope Larian does this, would be great
While her personality is bubbly, its clear that she's coping with the trauma in her own way (especially when she breaks down). Karlach is filled with hope, and is simply glad to be "alive" once again, free of Avernus and Zariel's service. Someone who had a life stolen from them being happy, upbeat but also brutal in combat ("Fuck yeah!" when it comes to smashing skulls), is kind of as good as it gets when it comes tot his kinda character, especially with how excellently Samantha delivered the voice acting. Its what makes it all the more painful that Larian overlooked the solution to her issue, its right there, everything you hoped for, and its not even accessible.
Here's to hoping for expansions and/or a Definitive Edition.
