They just needed to add one quest, hell, even half of the quest. Basically let us use enriched infernal iron, make it one trigger and call it a day.

They added not only cutscene, new dialogues and options, they literally added voicelines across act 2 and 3 that turned her into stage 4 cancer patient that knows they are going to die
