So I let Glendir out of the cell and asked him to follow me. Then I talked to Fiona about her brother and she gave me the quest. I talked to her again and Glendir but it does not seem to trigger anything. He is literally in the same room as she is. Did I mess up? Should I have left him in the cell then talked to Fiona for the quest before letting him out?
Quest: Rescue Glendir
Glendir is a half-orc imprisoned in a single cell in the eastern section of the caves. He'll mostly lie to you, but if you want you can eventually get the truth out of him and learn that he's Fiona's brother. You can also get a promissory note from him. Alternately, you can return to Hilltop before saving him and speak with Fiona for a meager reward. But the 200 gold she'll pay you may not be worth the trip. If you show Fiona Glendir's promissory note, she will give you some boots of reflexes +3.
Hope this helps
I didn't get any note from him. I just told him to follow me then I talked to Fiona who gave me the quest. Talking to either one of them does not trigger anything. They are literally in the same room.
