«All men must die, but we are not men»

DAENERYS TARGARYEN: You’re both here to advise me. I value your advice, but if you ever question me in front of strangers again, you’ll be advising someone else. Is that understood?
MISSANDEI: Valar morghulis.
DAENERYS TARGARYEN: Yes. All men must die, but we are not men.

George R.R. Martin, A Game of Thrones
