What does Bob say at the end?!

Rating: 9/10 (13 February 2006)

MAJOR SPOILER ALERT!!! I saw the film at the cinema and loved it, however watching it again the other night on DVD reminded me of the one thing that irritated me about it - you can't hear the last line of dialogue. When Bob races after Charlotte and whispers something in her ear it's all mumbles. I'm guessing you're not supposed to hear, and that thinking about/understanding what he might be saying is part of the overall purpose of the story etc., but it's just so frustrating and disappointing after getting to know the characters so well that we are excluded from this final and touching resolution between them - especially since whatever he says leads to their first proper kiss!! Did anyone else have this reaction?
