The prisoners have been plotting revenge for years, and recently the nephew of one of them argued with Scorpius. The boy was angry and let it out during a visit to Azkaban. Then, his grandfather took the opportunity to convince him to drink Polyjuice and swap their identities. This way, he could get revenge for both the Death Eaters on the Malfoys and his nephew on Scorpius himself."
