music behind the following scene

WEI BOYANG
So this is you, in the flesh? Both of you?

DR SAGE
It is, indeed.

WEI BOYANG
You have more hair than I had imagined, Doctor Sage.

DR SAGE
Call me Petronella, please. We know each other well enough by now.

WEI BOYANG
As you wish.

DR SAGE
Is my hair...?

WEI BOYANG
Oh, no. I did not mean to offend. I had simply imagined you to be
larger, with more severe personal grooming habits.

PROF SAVANT
Do not let her womanly visage and sproingy curls fool you, Wei
Boyang. She is a fierce as a tiger as stubborn as a mule.

DR SAGE
[Laughing] Erasmus!

WEI BOYANG
Now that I see her, I shall not imagine her as anything less than a small, but very determined liǎng.

DR SAGE
I'm sorry...?

PROF SAVANT
Dual-natured?

WEI BOYANG
Yes. Partially. It can indicate man and woman, or both sides. Colloquially it might mean sprite and monster. It is a word for when
two things are true.

PROF SAVANT
Oh, that describes Petra, perfectly. And what about me? Am I as you imagined, Master?

WEI BOYANG
You are indeed the man of learning I expected.

DR SAGE
Yes, that is our Erasmus - an open book.
