Robb is a man who can take a hint, and as much as he enjoys teasing her, he likes kissing her properly, too. So he doesn't answer for a moment, or ask about Sol and Venus and what exactly it is they're out here to see.

"What are we watching Venus do?" It sounds like a euphemism for something, for he remembers Venus being a name for a goddess of love, on earth. With Del, it's sometimes hard to know what to take literally.
