Wasn't Jack's daughter in every season, or did she miss one?
And I guess Chloe wasn't on season 1?
Placemarker for next week!
Chloe doesn't appear until Season 3.
The only people who have appeared in all 5 seasons are Jack, Tony, Palmer, and Aaron. Everyone else died in previous seasons.
Nina and Chapelle died in Season 3, Mason in Season 2, Michelle is presumed dead in 5.1 but she didn't come on the show until Season 2.
Now Palmer is dead and so is Tony. Aaron is a big ??? right now and Jack... Well, he's Jack so what more needs to be said, LOL!
