Arwen: (Renich i beth i pennen?) Do you remember what I told you?
Aragorn: You said you’d bind yourself to me forsaking the immortal life of your people.
Arwen: And to that I hold. I would rather share one lifetime with you than face all the Ages of this world alone. I choose a mortal life.
Aragorn: You cannot give me this.
Arwen: It is mine to give to whom I will… like my heart.
