AThe opening dialogue ("...and it's a story that might bore you...") is directly from the novel, but the closing dialogue ("...but in the end, all I could think about was...") differs from the last line in the novel, ("...but still I turn to her, my eyes interested, a serious smle, nodding, my hand squeezing her knee, and she"). It is supposed to add to the feel of randomness and disembodiment that is prevalent in the movie, and even more so in the book.Sharp-eyed viewers have noticed that during the last scene and only a few seconds before the cut, there is a road sign indicating an upcoming intersection. Given the bad weather and Sean's intoxication, it's possible that Sean was in some kind of accident, with the blackout symbolizing his death or being knocked out. However, since the dialogue is the same in the book without indicating a crash, this scenario is unlikely.
