However not every story needs, or should have the wines and roses happy endings.
Karlach going back to Avernus with Wyll and Tav seems actually happy to be there. The cigar scene to me is awesome. She can stay in the Realms but would have to accept being a Mind Flayer. While this might not be the life she desires it is a choice to live and then of course she can choose death.
I get that everyone wants every ending to be all smiles and giggles but the ending for Karlach, to me is not nearly as bad as people are making it. She has the chance to have two dear companions adventure with her and help her enjoy sweet revenge on those that hurt her. That seems a pretty good way to go forward in life to me.
My brother the fact your saying we need *every* ending to *all smiles and giggles* tells me your either not reading this thread or just ignoring whats been said and what were asking for. Giving karlach and actual *good* ending option (that doesnt force her back into the place she has spent 10 years in torture and trauma with or without friends) Doesnt in anyway i repeat IN ANYWAY take away from the endings she has currently. We are at most* hoping for her story to ne beefed up with added content cause hers is woefully lacking. And at BARE MINIUM allow us to use the very clear options presented in the game but denied to us due to lack of upper city/ time restraints- to actually fix her. Its great you enjoy her story and its conclusion but for the rest of us were hoping that larian fixes this VERY VALID critque.
