Good question! The VHS had a bunch of various home videos on it, and it triggered a memory in Nes. What we're seeing now is his experience of the event, not the literal video itself. :)
It's okay! The answer is 2005. This was subtly hinted at with the height markings on the wall on page 35. The writing style changes to match the boxes in the room. This story takes place in 2015.
Once again, you pushed yourself art-wise with these poses and angles. You never cease to impress!
But man, this only drives home for me how Nes must have felt seeing his might superhero of a father succumb to his illness. Must have been earth-shattering.
