I had the same problem, but a bit different. I didn't do the dark brotherhood quests, but i DID take the quest from the dark elf shopkeeper to break into her house. After that, she didn't appear. I used the console to make Viola appear in front of me, using the following command: player.placeatme 00014129 It should place Viola at your position, and she SHOULD go about her normal routine. If that code doesn't work, use player.placeatme 0001B13C I hope this helps, it worked for me. edit: Oh, and it may be obvious, but i might as well say it: You shouldn't spawn her inside her house, she might report you as trespassing. I'd do it on the street outside her house.
