((I can also confirm, for those curious, that regardless of whether you don't interact with the mindflayer, interact with it and leave it alive, or even feed it your brain so that ti's very alive, and then run away..... It doe snot change or affect anything in the shattered sanctum scene with dror ragzlin. In fact, you can have him speak to the dead mindfalyer, after feeding it your brain in the wreckage, and then hike back to the wreckage and still find the healed mindflayer very much still alive and still hostile to you. this is sad, I wanted a hidden altertnative route.))
