Still, in a game where basically everyone can have happy ending or at least semi happy, only one character being locked out of it (despite her problem being quite easy to fix lorewise with many different options to do so) is a very poor and distasteful writing. Plus "real life" argument. Yeah, I always like to be listen about realism and real life in a game where I try to get Cthulhu out of my head, take part in a space war and literal divine interventions happen on daily basis. Very realistic all of that. And it's not like the premise of d&d is having fun and bending the rules as much as GM allows you, we totally need grimderp forced tragedy for ONLY one companion
