Robert Eddison: Grail Knight
Grail Knight : But choose wisely, for while the true Grail will bring you life, the false Grail will take it from you.
Walter Donovan : [Elsa selects the gaudiest cup in the Grail Chamber, for Donovan] This is indeed the cup of the King of Kings.
[He drinks from the "Grail", and proceeds to age rapidly]
Walter Donovan : What's happening to me?
[Panicked, he grabs Elsa while transforming into a hideous aberration]
Walter Donovan : Tell me! WHAT HAVE YOU DONE TO ME?
[Elsa screams in horror as Donovan becomes a skeletal monstrosity, which Indy wrenches away from her. Donovan is thrown backward and reduced to a cloud of dust, which drafts carry from the chamber]
Grail Knight : He chose... unwisely.
Grail Knight : I knew you'd come. But my strength has left me.
Indiana Jones : Who are you?
Grail Knight : The last of three brothers who swore an oath to find the grail and to guard it.
Indiana Jones : That was seven hundred years ago.
Grail Knight : Long time to wait. You're strangely dressed for a knight.
Indiana Jones : What exactly? A knight? What do you mean?
Grail Knight : I was chosen because I was the bravest, the most worthy. The honor was mine until another came to challenge me to single combat...
[offering his sword to Indiana Jones]
Grail Knight : I pass to you who'll vanquish me.
