I read that same comment about the "I love you" a while back and kept it in mind when I watched my new DVD last night (it finally came last night, Yeehaw!). And, my conclusion was that it's just the breathing. Maybe you could project an "I love you" into the sound of the breathing... but it's a stretch. Awww, but we know he's saying "I love you" in his heart.
Hey! I have an idea, maybe we could start a new controversy like the "I"m sorry" second-tent scene debates. Fun!
