During the climax of the 2003 movie, Lost in Translation, the central characters, Bob & Charlotte share an emotional moment. During that time, Bob seems to have said something into Charlotte's ears, to which Charlotte nods. After that they separate and the movie ends.
Wikipedia says "Bob embraces Charlotte and whispers something (substantially inaudible to the audience) in the tearful Charlotte's ear. The two share a kiss, say goodbye and Bob departs."
What could it be that he said into her ears?
