Oddly enough, I don't really see Sam Carter as being the jealous type. Sitting Rory down and picking her brain and then putting her to work immediately on some of the problems they've not been able to make headway with? In a heartbeat. You might want to check out the SG-1 episode "Prodigy" in this regard, this is where they introduce Lieutenant Jennifer Hailey, who is actually as brilliant as Sam and possibly even more so.
