It is sad. But you know, I'm glad we got to watch it all. It was a great ride in the end. Bittersweet ending. I think he had this set up many many years ago. But he just didn't have the way to put it out. Jack is a hero and tragic things happen. But he got to see the love of everyone he saved. He fell in love which will be with him forever. All that time, he was fighting for everyone,but didn't have that spark of love. I think it's kind of a fitting end for our Jack.
