Which year was Dollar born?
So we see the baby Dollar being born in the '1999' part, but then in '2014' he is shown minor than a 10 year old boy, when he would be around 15. Since the main characters (Tao and her two friends) doesn't change a bit during that span of time, I thought ...well, ok. But then during the '2025' part, Dollar claims to have not seen his mother since he was 7, so... I guess we are supposed to asume that during the first segment of the movie, 8 years passed to have the baby born, in 2007.
Great movie btw, I enjoyed especially the third act.
