Down the darkened back alley, about five or so meters behind the crates you hide behind, is a door. Its closed, and generally nondescript...even painted the same colour as the wall. In the darkness, it would actually be tough to see without your mask to enhance things.
For about ten minutes, you sat and waited. Only a couple of humanoids could be seen passing the alley, and neither of them even slightly glanced down towards you. Not long after, though, a soft blue skinned Duros passes by. He passes by once, then a few minutes later, walks back, this time turning and slowly heading down the alleyway.
As far as you can tell, the Duros is unarmed. You're also pretty sure its not the same one you saw in the cantina.
