In a world where people can walk on walls with the same ease as walking on the floor, a person named Zephyr is standing on the north wall of a square room and facing towards the center. There is a painting hanging on the wall directly opposite Zephyr. Jehan is walking on the south wall, also facing the center of the room, and is directly in line with Zephyr and the painting. What will happen if Jehan walks straight towards the painting?

Respond very briefly.
Since Jehan is walking on the south wall and facing the center of the room while Zephyr is on the north wall also facing the center, they are directly opposite each other with the painting in between. As Jehan walks straight towards the painting while remaining on the south wall, they will get closer to the painting. Meanwhile, Zephyr, positioned on the north wall, will see Jehan approaching the painting from their perspective, upside down. However, Jehan will not pass the painting or reach Zephyr's position unless they physically move from the south wall to the north wall. Jehan's perspective of Zephyr would remain as seeing Zephyr standing upside down on the opposite wall. If Jehan stops at the painting, they would be able to see it right-side-up from their position, while Zephyr, on the north wall, would see the painting upside down from their perspective.
