the thing is, it is a very real possibility. last year rda did say he'd like to scale back his work a bit to spend time with his daughter...now don't all get in a panic or anything, but if you had a choice to stay an actor, 14 hour days and all or be exec producer, which also has long hours but more money and prestigue...which would you pick?
it is extremely likely that changes might occure for season 6 & beyond. some actors might not want to stay around, things change...so let's just have fun with this, what if, let's say jack got hurt and couldn't go through the gate anymore, hammond retires and jack is now running the place.
who will get command of sg-1? sam or someone else?
and who could that someone else be?
kevin sorbo, david duchovney, what's his name on third rock from the sun, your next door neighbor...
who would be the ultimate jack replacement?
