In the lead-up to Halloween horror shows continued to rule the cable airwaves. The Walking Dead and American Horror Story had dominating nights once again, while on broadcast the usual suspects (The Big Bang Theory and Once Upon A Time) put up more strong numbers.

While talking with Nerd Nation, popular comic writer, Marc Andreyko, may have let a rather large piece of news slip concerning a certain major figure in DC comics making an appearance very soon on the CW's show, Arrow.

The CW has scored a ratings and critical hit with the dark hero drama Arrow, and fans got a potentially game-changing shock in last week's episode. Oliver Queen's (Stephen Amell) secret is out, and according to executive producer Andrew Kreisberg, it's going to change everything. Spoilers ahead!

Last week, the big story was The Walking Dead's stellar season two debut. This week, American Horror Story returned for its own record-breaking performance. Meanwhile Arrow stayed strong, Big Bang Theory kept dominating Thursday nights, and Last Resort and 666 Park Avenue both continued to struggle.
