Is There a Light at the End of the Tunnel for 'Dexter'?

CBS Special: The 67th Annual Grammy Awards on CBS at 8:00pm ET. Special presentation. Earlier today I couldn’t remember if it was the Super Bowl tonight, but it is the Super Bowl of music!

The Real Housewives of Potomac on Bravo at 8:00pm ET. Ninth season finale.

All Creatures Great and Small om PBS at 9:00pm ET.

Anne Rice’s Mayfair Witches on AMC at 9:00pm ET.

Dexter: Original Sin on Showtime at 10:00pm ET. Two weeks left after tonight, and I still don’t see any news about a renewal. But then again, given the framing device, how long can it really go on?
