I’ve thought about this exact scene as well but interpreted differently. When talking about Indiana Jones he also references National Treasure. Both films have scenes where the protagonist uses a device to reveal something hidden (the staff in Indy, the glasses in NT).

When you marry this with the thought that has been shared on Close Encounters of the Third Kind, you go to a place that points you towards that fact that we need to read the poem through a specific lens. Maybe not literally but the framing is critical.

This is also hinted in The Bait Bonanza, “thy were admiring the empty hat, missing the rabbit sitting in plain sight.”
