I just wanna point out once again that Karlach returning to Avernus doesn't imply she will be under Zariel influence at all, even more so if Tav and/or Wyll return with her.
While i also want an ending where she is completely saved with no strings attached. If one wants a better ending to"Return to Avernus" path, at least give us an epilogue along the lines of:
Quote
As for Karlach and [TAVNAME], returning to Avernus made the love between them burn ever brighter in the face of the perilous nature of the Asmodean Underworld. The couple would stir enough trouble that their names would reach the ears of even the higher circles of devil society. In their search for a cure for Karlach's condition, many dangers would need to be toppled and impressive feats would need to be performed, but with a commitment to each other that transcended even the very planes of existence, that wouldn't stop them.
But that, as the saying goes, is a tale for another time...
Put a static image of Karlach and some music in the background and presto, you have a follow-through on the ending we got.
