Lost

Lost's Ajira Airways Flight 316 yielded some strange but important passengers. While Caesar, the de facto leader, turned out to just be a man out of his league (he was killed by Ben shortly after the plane crash), it was the mysterious Ilana that seemed to really be in control. Along with Bram, played by Brad William Henke, Ilana led a group of survivors who seemed to be working for Jacob, and had been working for Jacob for quite some time.

Ilana was last seen dumping the real Locke's body out of a crate and onto the beach, revealing the prescence of Jacob's nemesis to Richard Alpert and the rest of the others.

We'll be seeing plenty more of Ilana next year -- DarkUFO has recently confirmed that actress Zuleikha Robinson, who portrays Ilana, has been promoted to a series regular for the sixth and final season on the series. This is great news, mostly because we'll get to find out why Ilana was so bandaged up during that visit with Jacob, how she knew Jacob before, and how she came to work for him.

I'm very excited by this new development. Robinson is the third new confirmed regular for the sixth season; Nestor Carbonell (Other Richard Alpert) was the first, and Jeff Fahey, who plays  pilot Frank Lapidus, was the second.
