...they not actually met up in '99.
Somehow pops was already diagnosed as having terminal cancer due to his smoking so they knew he'd never survive until '99.
So pops and son, right before the Aurora disappears and they lose contact, say their final goodbyes and regrets of not being able to see each other one last time. Next they softly cry with no words left to speak.
