Question: Michael Vartan is supposedly signed to do four more episodes of Alias. Will it be as a ghost?

Answer: OK, major-ass prattle here: According to Pinkner, Vartan is actually returning for five, possibly six, episodes, beginning with the second one back this spring (that's Episode 99, for those keeping track at home). And I'll let Jeff address the second part of your question: "As we've said from the beginning, the rumors of Vaughn's death were nothing more than rumors. In this world, don't take anything at face value. We'll know by the end of the 99th episode exactly where he is and if he's alive or not."
