After reading all the data mined cut content related to Karlach and her endings, it's clear that:

1) Karlach was always going to die (even if Illithid, her heart was going to burn her up!)

2) Larian cut scenes that would have provided a lot more closure with the companions


I'm surprised she was always slated for death given all the clues in Act 3 that her engine could be fixed. Makes the narrative inconsistency all that more disappointing.
