Astrid and Walter in “Unfinished Business”

Astrid

What am I looking for?

Walter

Anything that looks like it doesn't belong.

Astrid

I think this qualifies. Richard Nixon on a silver dollar.

Walter

That's disturbing.

Astrid

So when you separate them, Walter, how are you going to tell them apart?

Walter

Mr. Pratchett from over there was married, he was wearing a wedding ring.

Astrid

So as far as his wife will ever know he just disappeared? That is so sad. Wow, look at this. It's a double-decker car! Does this mean they drive these over there?

Walter

I suppose so.
