In the midst of this sea and on the edge of this desert.

 
For some reason I'm a little fixated on this line from ep. 30 of Welcome to Night Vale:

 lovely Carlos, with his perfect teeth and hair and penchant for sometimes chewing a little more loudly than is preferred

 I just love that little hint that Cecil is starting to notice the less than perfect things about Carlos. Its also made me wonder about all the other people that Cecil might previously have thought were perfect and has since amended his opinions about. My favourite choice is Steve Carlsberg, on the sheer amount of unreasoned vitriol Cecil employs when talking about him.
Excuse me while I just go make my way through the Cecil/Steve Carlsberg tag. Already 73 entries! Go fandom go! I would love to find a fic where Cecil is going on about how perfect Steve is.
I would also love a fic where Night Vale residents were so desperate to cheer Cecil up from a previous break up that they came together to lure Carlos to Night Vale to do science enticingly in front of their radio host.
