Breaking news! Ginny was not saved from death, her clone was. The real Ginny had been captured by Voldemort and was being held prisoner until Harry Potter was sent to him, along with mittens and chocolate. Voldemort was not happy with the Thin Mints and Hershey's chocolate he was sent, so he made a clone of Ginny, gave the clone to Dumbledore, and turned the real Ginny into mittens.
