but he got over mal, so wouldn't getting over Mals death signifies as letting her go, Thus the ring would disappear as she dose in his dreams. His kids look the same, same clothes too, they just turn around, maybe him coming to truth with mals death ect ect enabled him to see his kids faces in his dream but he had to lose a part of him self to do that, and that was mal, so the ring disappeared with mal. I'm torn between reality and dream, as I hope its reality. The ending was definitely left open for debate
In the scene with old saito, which takes place afer letting go of Mal, he still has the ring on, so no he would still have it apparently
Its not said in the film how long its been and thus how different the kids should look age wise, however IMDB lists two seperate kids used for his children, with the age difference stated in the name of the character, and that being 2 years apart. So i guess that means it has been 2 years and the kids should be older. So who knows
