Harry found that rather hard to swallow and more importantly, didn’t believe it. The timing of Draco’s disappearance was too significant. Hours after one of their worst rows, where they both said hurtful things that they probably meant but could have phrased better. More sensitively, it was mere weeks after Draco’s wand had been snapped, and the following realisation that the Ministry had developed a cruel little spell that inflicted burns to any wizard or witch who attempted to use magic with a different instrument. Provoked crippling nausea even around some magical objects or in some particularly magically imbued settings, like Gringotts. Like an induced magical intolerance.
