That's a little tricky to figure out precisely (although Femme probably knows), since we base our years on a 365-day, 24 hours/day annual clock, and it;s unlikely that many of the places Femme's been have that exact year time frame. At a guess, I'd say she's somewhere between 60 and 80 Earth years in age, but could be a bit older.
Well done Clark. The further this date goes on, the more it becomes clear that his remark about his IQ being inversely proportional to the beauty of the woman he is talking to only holds for first contact.
I think the first date is nearing its end? I look forward to see how they wrap it up and say goodbye, but not nearly as much as I look forward to both of them checking in with their friends for some reason... :D
