This (http://community.livejournal.com/dexter_fanfic/1867.html) is the only Rudy/Dexter fic I've seen. And then there's this (http://community.livejournal.com/dexter_fanfic/2798.html#cutid1) series that I haven't read yet. Ooh, and I just gotta rec this (http://frayen.livejournal.com/274194.html) fic too, even if it isn't Rudy/Dexter, but it's a crossover with SPN and it's so damn good that I have to rec it to everyone, haha. :D
