But is it really too much to ask for a happy ending? Just as easily, right after being transferred to hell, Zariel could appear, effortlessly kill Tav/Wyll, and force Karlach into further servitude.
To be fair this event is actually surprisingly unlikely, rather, Tav has a soul and souls are very valuable to an Archdevil so they would likely try to contractually bind them above all else instead of just outright killing them.
Of course, you are right, but that doesn't change the fact that, as I mentioned earlier, "maybe yes, maybe no." If I have to choose between these three pathetic endings, I also choose the trip through hell. And of course, we can write it ourselves that it was a quick action, the engine was fixed, and a return to Faerun occurred. However, I would prefer not to have to write that for myself because it's glaringly obvious that this is how the story should end if someone wanted to save her.
