Let me be the first to say, I SURE HOPE SO. I love Dexter and Deb's chemistry, brought to life by the real relationship between their portrayers, Michael C. Hall and Jennifer Carpenter, who were married for a couple of years. Yes, the relationship is totally taboo, but, hello, this is a show about a serial killer. Everything about it is vaguely f**ked up. Anyway, I think this totally shocking twist is something that the show will pursue in greater depths next season, especially since this season ends next week. Dexter and Deb do have a very special relationship, one that he will never have with anyone else considering his ... limitations. And purely from a psychological point-of-view, I think the idea of there being romantic/sexual feelings between non-blood siblings is something "Dexter" would do a good job exploring. Or maybe I just want Dexter to get laid really badly and don't care who it's with.
Incest of the sorta-sexy variety in TV and movies is more common than you might think. Here is just a brief overview of those (consensual!) incestuous relationships that didn't make our stomachs turn.
