He hid his discomfiture in another sip of the tea, widening his eyes in surprise. He was normally better than that. "It is my mother's language, I believe. Or so they told me when I was a child." That was at least true.

"In polite company, I can say only that my enemies speak about me only in the language of the dead." Which he could technically speak. But the dead are more boring than people think.

But also...that was ALSO not supposed to be something he admitted, especially to a near stranger. Especially pretending to be Harmless Silly Dilettante.

He looked at the tea, suspicious.
