Memory dust is not enough to undo the damage caused by Wyatt's conjured dragon as it attacks people and vehicles in the city by the bay. Instead, the Cleaners are introduced as the masters of memory erasing and undoing what was. All traces of Wyatt have been wiped out. Yet, Piper senses something is wrong. She has her maternal instincts fully on display whilst helping a father with his groceries. Leo hears the sounds of a baby. Ultimately, the Charmed Ones conclude that someone is messing with their minds and cast a spell to relive the previous day. The Cleaners are outed and the Charmed Ones demonstrably explain that they will clean up their own messes. Round One goes to the Charmed Ones. The Cleaners will not be so forgiving next time (in Crimes and Witch-Demeanors).
