So I came upon the two poor souls locked up in the Dark Moon Monk-temple, the riddle seemed like a familiar one and I asked what I thought was the correct question. However, when I tried to open the door it was locked. I proceeded to use Knock (since I'm all out of thieves for the moment) and the door flew open. I then openend the other in the same way. At this point I would have expected something to happen - either a conversation where the two prisoners are happy that they have been rescued or a major trap going of, but nothing happens. If I try to speak to them I just get the "X has nothing to say to you"-response.
Is this a bug, or have just done something wrong?
Btw, sorry if this has been explained before. I have tried searching, but I couldn't find a response to this.
