The season finale of Dexter. Overall an awkard and uneven season, but in the finale...
SPOILERS!!! (left click and drag below to read):
...it ends with Deb finally seeing Dexter commit a ritualistic murder. Granted it's just one murder, of the man who kidnapped Dexter's son. Plus, it's revealed Deb's in love with Dexter, despite him being her adoptive brother. Really looking forward to how this shakes out next season. Personally I think Dexter will get by with the murder; after all it's just ONE murder Deb's seen, and it could be seen as "justified." Me, I really hope Dexter finally comes clean with her, about him being a sociopath and how Harry trained him to focus his murderous instincts only on those who deserve them. Though I doubt that will happen, because the show's already been renewed for two more seasons.
Anyhoo, an excellent finale to an otherwise disappointing season. Can't wait 'til season 7.
