Cruel Justice (Spoilers!)

[Avatre]

So, having released the mage when I first rescued Octavia and Regongar, he's now at the tavern instead of the dwarf offering a back way in to Maestro Janush. Is this supposed to play out different to going in the front way? With the locked door, I have to go around to the front anyway and he still gets away, is the key to that door somewhere near?
