Er, I may ship brothers even less than Riona. Riona will, on occasion, write twisted and wrong Sam/Dean. I don't, and only read Sam/Dean if it's written by Riona (tried poking around at other Wincest fic once, and was completely put off). And I may even write het (and be plotting to write Dean/Bela femmeslash, where Dean touches the artifact that men aren't allowed to touch, suffers the consequences, and winds up having a weird, slightly sex-laden adventure with Bela to retrieve it and switch back. If I can figure out whether Dean would make the "Sam, I've been turned into a chick," call, and how long it would take Sam to stop laughing).

So non-Wincesters are creeping onto your flist.
