I listened to what she had to say, and then my character found the hidden entrance. When i entered is when Aunty Ethel turned violent and changed forms and summoned the redcaps. I killed those, then chased after her. Went through and looked at all the things she did to people, talking to the door to let me through (passed my check), before going and killing the 4 people in the next room. Instead of jumping down, i threw items on top of the gas plates to stop the gas from releasing. When i got to the fight area at the bottom is when she triggered yelling at me and cursing me. After that, the fight didn't trigger, but Aunty Ethel was there and i was able to kill her. I then freed the girl (who was ungrateful btw).
