What a cop-out. First by making the ring return mean "come get me" instead of the obvious "we are through", and now by having her plane turn around just so they could meet.
There was no need for any of that. Just have him lose the finals, believe that it's all over so there's no point in saying goodbye, have his epiphany, and then reach her just as the final call is being made. Much more believable and just as sweet. You could even have him take the ring from her neck and place it on her right ring finger, for the extra punch.
Anyway, great ride all around. This title will certainly stay with me. Hopefully, there is some sort of prologue where they meet or something.
