2013 arrives this week and brings with it the premiere of the final season of Merlin, new episodes of Once Upon a Time and American Horror Story: Asylum, and some worthy marathons to keep you warm on a cold New Year's Eve and Day.

Also this week, Sheldon gets accused of sexual harassment on The Big Bang Theory, Finch goes back to school on Person of Interest, Holmes offers Watson a job on Elementary and there's a new Star Wars: The Clone Wars.

Here's what we have to look forward to this week on sci-fi, fantasy and paranormal TV.
