You can now take the Hands Off quest. To do this, you need to talk to Balder, who can be found at his table - next to the quest "Eli's Weapon". It is marked on your map as part of the Request for Help, so it shouldn't be too difficult to find it.
After mentioning Eli, Balder will warn you not to interfere with his duties, after which you can take the quest you need from him.
Now all you have to do is wait. Just leave and complete other quests, returning periodically to check Eli's cell to see if Balder was there.
