This is from Kristin on EOnline.com from October 1, 2005:
10/01 - As you can probably tell by last night's episode, Michael Vartan is no longer a series regular on ALIAS. Howevah! They are WORKING ON getting Michael Vartan back for 1-3 episodes this season ... but so far, no deal. As I understand it, the ball is in his court. I have no idea as to HOW they would bring it back ... but remember, ANYTHING can (and does!) happen on Alias, and JJ's words just keep ringing through my head: "The Vaughn storyline is NOT what it seems."
I dont know about you but 1 to 3 episodes is just not enough. He is an essential character.
Also, why wouldnt Vartan want to come back??!? Maybe its Jennifers marriage to dear ol' Ben? Or the fact shes preggers with Ben's baby?!? Could he just not come back!?!
This is just not cool.!
What do you guys think!?
