If Ben wouldn't be considered part of the Oceanic Six would Aaron?

Anyway I've heard the Jacob thing really won't be tied up till the end of the show. And Michael's definitely back and something about finding out who was in the casket at the end of season three.

I would have to say yes, since technically he was on the plane, he just happened to be inside Claire at the time.
