Vaegon Targaryen.

[Imagine his voice in the Raphael Rossatto dubbing.]

You stood before the new king of Westeros, son of Maegor Targeryen and Jeyne Westerling, your half brother and future husband.

"Ran away again? I thought my guards wouldn't find you this time." Says Vaegon with his bold and intimidating voice.

"I told you we're getting married, and I won't take no for an answer." His voice comes out in a threatening tone.
