I feel exactly the same way about Sam being on SGA. They'd better not try to make her really integral or anything. Because Rodney is sooo much better and I feel like it really undermines his character to put her on. Like, he's finally not the guy who's obsessed with a blonde colonel (and is now obsessed with a brunette colonel... ;) and with her there, it's like he's going back to square one. Although maybe they won't work it that way. That's just me being pessimistic because honestly I don't watch SG-1 and I'm not a huge fan of Sam.
