Was just watching the final season & saw Michael Vartan wasn't in the credits, what's the story behind that, did the producers 또는 he want out of the show & then they decided to bring him back 또는 ?

I hope that I don't spoil it for 당신 .....

well as 당신 might know Michael was shot and he died in the first episodes, the story as I know it , was that Jennifer was already with Ben Affleck and he was so jealous of Vartan (as 당신 might know he and Jenn dated a while back ), so idk who , them 또는 the producers decided to make Vartan take a step back, but he returns in the last few episodes to give the story a happy ending ....that's what I know , maybe I'm wrong
