This line was buggy on both my run throughs.

The first run through, it got stuck, I couldn't find Ethyl after she ran through the fireplace. I let the girl out the cage, but she wouldn't talk to me.


The second run through, I killed her before she had a chance to run through the fireplace, and when I got down to the bottom near the cage, her corpse was there laying on a bridge. Unless there is some reason there should be two corpses. I was able to talk to the girl so, that while immersion breaking, it didn't stop the quest line.
