This made me smile right up until the end, when it made me oddly uncomfortable.
It falls a little too close to stereotypes. The educated, interesting, curious boy-scientist who wants to explore the world and the charmingly naive, ignorant girl. It's too easy to point and laugh and say, oh ha ha, girls are so stupid! And I know that's not the intent of the strip either. But to someone, it's as unsettling as if the second character were a minority race.
