Sci-Fi This Week: Arrow Meets The Flash, Haven‘s Audrey Discovers Her Origins

December has arrived, the air is crisp, and Christmas is coming … and that means many of our favorite fall shows are wrapping up. Some will be gone until next fall — but, fortunately, most will take a holiday hiatus and come back in the new year.

Mid-season means that there are some fun highlights on sci-fi and fantasy TV this week. On Arrow Barry Allen arrives in Starling City, beginning a path that will lead to the birth of The Flash. Audrey will learn the truth about her origins on Haven, and on The Tomorrow People, Stephen will get closer to finding his long-missing father.

Sleepy Hollow and Agents of S.H.I.E.L.D. are taking the week off. And if you’re looking for info on Revolution or The Walking Dead, both are on hiatus until early next year.
