William: …and then Austria-Hungary is Wilhelm’s lap dog…
Integra: Don’t get into it, Heinkel.
Heinkel: But they can’t talk about Austria-Hungary like that! It can’t help needing an ally. Its military is so weak and it’s next to Russia. If Germany’s the only country that will back it up, then…
William: Oh, how cute! Look at you, trying to talk about international politics with the adults! Isn’t it just so sweet, Emma?
Integra: On second thought…never mind. Carry on.
