wait yall I CRACKED THE CODE
remember how they never found kou's body? it's likely because he went on to live in the present from then on!!! kou went back to the past to settle his feelings AND continue the timeline AND THEN went back to the present. cause again, NO BODY WAS FOUND EVEN UP TO THIS DAY!!! that could only mean he went back to the present, with shirou!!!!
this is definitely it everyone, im not huffing copium here!!!! it makes the most sense!!!!!!!!!
