"Well, it's very obvious that you're hot," Rodney tells her with a touch of asperity. He's not registering the distinction between 'know' and 'see,' because he's a firm believer in empirical evidence.

He nods along with her list of things-about-her, though, and perks up a little bit at the eighteen languages thing. That's an excellent sign of intelligence and maybe he's shallow, but the fact that it's more than he can speak suggests she might not immediately fail to be an intellectually challenging conversationalist. He subconsciously shifts her from 'random blonde who kissed me' more into 'someone who I might actively engage with as an individual.' He ticks a notch more comfortable around her.

His eyes widen at the 'dead' thing, though. That sounds suspiciously like the nonsense he'd gotten up to with the SGC. He answers her question, his mind half on the 'dead' thing and still faintly preoccupied with Jennifer, by mushing them together and saying, "Oh, no, I almost proposed once before I realized I couldn't do that to her and I was well on my way there again before the Storm caught me up, but never actually married, either. Seriously, though, dead? Were you resuscitated? Or was there some fancy CIA technology involved?"
