That's a good question, but I dont think it's the "son", I think the figure is the sun and he appears to be moving through the mazzaroth, or what we know as the Zodiac which is how the sun travels along the ecliptic in the sky.

I know that some people identified the area where he gazes at the end of the video as possibly Scorpio. The sun will be nearer Scorpio around the winter time, around November. If he is indeed gazing at Scorpio ahead of him,that would indicate that the events are over before winter ends and before the sun moves into Scorpio.
