He knows my birthday! He could've 
killed me at any time if he wanted to.
Er kennt meinen Geburtstag! Wenn er wollte,
hätte er mich jederzeit töten können!
¡Conoce mi cumpleaños! ¡Habría podido
matarme en cualquier momento!
¡Conoce mi cumpleaños! ¡Habría podido
matarme en cualquier momento!

Conosce la data del mio compleanno!

Ele conhece o meu aniversário! Poderia ter
me matado a qualquer hora se quisesse.
