The gray moments at Wendy's home/window are moments in his past when he was at his own window, trying to return ホーム but his mother did not see または hear him, just walked away. and there was another child sleeping in his bed.
This is my third PP video to this song. This is actually the first video from me ever where Wendy really has grown up but Peter hasn't. My Peter Pan 動画 are also viewable at link
Peter and Wendy both wanted each others to stay, especially Peter needed her to stay. This is shortened from the intro as it was a bit too long for a video.
Peter's grown up after all but not really grown up, basically just grown older but still is the same emotional mess 'cause he can't let go of what happened with his mother not to mention open up about it.
