This is a man looking into the future - his own, and the future that will happen when he will no longer be.
This is a man looking into the past - seeing his own features from 30ish years ago, seeing his family tree, seeing an event that has happened billions of times before.
This is a man looking at his own immortality, and at a reminder that life, amazing as it is, is terrifyingly fragile.
This is a man looking at his firstborn child, on the day of her birth. This is the moment he falls in love, headlong, utterly, and forever.
(This is also a man who will confused and out of the loop for the next ~23 years.)
Congratulations, P & L. Love.
