There's trouble ahead on Dexter Season 7. Based on the final scene of Season 6, this doesn't exactly come as a surprise.
But the challenges facing our favorite serial killer will not simply come in the form of what Deb now knows about her brother. He'll also face obstacles and storylines created by such guest stars as Yvonne Strahovski, Ray Stevenson and Jason Gedrick.
These actors will come on board this fall as a mysterious woman named Hannah, a Russian mob member named Isaak and a strip club owner named George, respectively.
