I keep running into issues with optional dialogue when enemy is below certain HP threshold is being skipped. First it was with Fezzerk, I killed him before he was able to beg for mercy and now its Auntie Ethel. Karlach at level 6 just squashed her, she did not have a time to utter a word. This had an unfortunate consequence of forcing me to knock out the masked combatants, as the fight just kept on going.

Is there a work around I can use?
