2. The missing ghoul's girlfriend. Where is she? I looked everywhere! Also, I'm pretty sure he turned hostile on me for no reason! I just ran. 
She's hard to find. You have to find the Nightkin Jailer (that's the actual NPC's name), then you know you're headed in the right direction. I got pretty turned around, but I found her.
Also, I found that he turns on you if you try to go to the upper level of his room. I guess he's really on edge? Just don't go through the door that leads up the stairs.
