Liked this. A lot. I think you really captured a certain mood that flickered through that brief scene between them in CN - and drew it out to a scenario that I can imagine. 

This was taking what you could get.

Great line. Just sums up the melancholy feel of the  symbiotic situations they found themselves in that night. As does the business with them sharing the cigarette - knowing they shouldn't, but resigned to the fact that...it is what it is. Really well done.
