Stupidity: Stephanie googles (using the actual Google engine) the name of Emily's fiancé but gets zero results. He is the heir of a mob family embroiled in decades-long feuds, a central figure in the Roman nightlife travelling with private jets, with the newspapers having covered their earlier relationship. Therefore, the chances that absolutely nothing exists online are exactly zero. (00:19:05)

Stupidity: Alex is the only child that did not go missing. No one has seen his parents, and he is presumably still at risk, but neither the police, social workers, nor the school think to do a home wellness check, where they would have discovered the newspapers covering the windows.
