The short answer
One trader and two mirrors start on the large left island. The mirrors sit diagonally apart, one lower-left and one upper-right. A brown boulder is on the lower-right island, and two exit circles are on the separate top island.

- Push the lower-left mirror right until it is one tile east and one tile south of the upper mirror. Stand immediately left of the moved mirror, directly below the upper one. When two trader previews appear, activate reflection to create both traders (4:30–4:31).
- Move the pair left so the upper trader pushes the other mirror one tile west. Move down around the right mirror, then push that right mirror one tile north. Both mirrors now share a row (4:34).
- Move down and left. The lower edge holds the lower trader while the upper trader reaches the west side. Walk around the western mirror until a trader is north of it, push it south, then get to its left and push it right. Stop directly below the eastern mirror at the island’s east edge (4:39).
- One trader is below the lower mirror and the other is to its left. Activate the reflection that places the aligned trader on the right island. Move the remaining trader down to the left island’s southernmost extension; its image reaches the right island’s westernmost square. Activate again to bring both beside the boulder (4:43–4:44).
- Move down around the boulder to its south side. Push it north into the water gap below the top island. Cross the submerged boulder and place one trader on each exit circle. Both circles are occupied at 4:57.7.
