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.
