Bruce and Ra's Al Ghul in “Avatar”

Bruce

You've got a serious priority problem, Ra's. What can be in that tomb that's more valuable than the love of your daughter?

Power, detective. The power once held by almighty Thoth-Khepera, Queen of Two Continents.

Bruce

You surprise me, Ra's. The world's oldest chauvinist chasing after a woman?

Thoth-Khepera was not simply a woman, detective, nor merely a ruler. Through her flowed the power of the gods. With no more than a gesture, she controlled the force of life and death, and with it, she kept a nation under her thumb for one thousand years.

Bruce

You sound like a bad Saturday afternoon serial, Ra's. This is sheer nonsense.

No, detective - I know there is a power there to be tapped! My six hundred years of life are proof of that power.

Farewell, detective. Farewell, Talia. It is said that one finds one's immortality in one's offspring. Alas, I know that to be a lie.
