I really like Sam on SG-1 but was also concerned about how she'd be on SGA. I understand why she's not in some episodes; what annoys me is that no one even refers to her in episodes where she doesn't appear, which leads to oddities like Sheppard apparently deciding on his own to meet the RepliTeam. They should at least have a nod to Sam, I think.

I feel the same about Ford; I wish we'd see him again occasionally, though. I'm afraid they're doing the same thing with Elizabeth: a little while and we will see her no more. Just when she's getting really interesting, and I think the actress has really grown in the part!

I miss Carson a lot and want him back! I don't want Keller to go either, though if it came down to a choice, I'd surely pick Carson. I don't know why the writers feel the need to eliminate characters (why, oh why, did they have to say the Ori had taken Kelowna? Why kill off various people near the end of SG-1?). I think it would be (will be?) fun to see Carson and Keller together!
