I broke into the Argonian Assemblage, as I am wont to do, and found Stands-In-Shallows wandering around. I got the quest to grab the double-distilled skooma for him, went and got it, and came back. Now, I did this mistaking him for Scouts-Many-Marshes, thinking I needed to do this to open up light armor training. No big deal... except the door is always locked, and neither of them have yet to come out despite my waiting for basically an entire day. Only two of them (Neetrenaza and Shahvee) exited, and if I break in again they start yelling about how I'm not supposed to be in there and won't talk to me.
So what do I do now? If I leave the city for a while and come back, are they more likely to be outside? It's the only thing I can think of at the moment.
