TV THIS WEEK: Once Upon a Time, Revolution, Walking Dead and more!

It's Thanksgiving week, so that means there won't be a lot of TV sci-fi originals, but you'll still be able to catch some significant viewing as things heat up on Once Upon a Time and the soon-to-exit 666 Park Avenue.

Also this week, Revolution rocks to Led Zeppelin, Ghost Hunters goes back to school, Blood Face's past is uncovered on American Horror Story: Asylum, things get ugly on Syfy in Dungeons & Dragons: The Book of Vile Darkness, and Rick's sanity snaps back into place (or does it?) as he discovers some of his own are in trouble on The Walking Dead.

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