It’s a lesson that Bellatrix learns quickly. Not even two nights after their little session in the pool it is impressed upon her that this creature is no mere spirit; Hermione is not locked to one location or persistence, she is able to throw herself wherever she wills due to power and experience. Whatever magic it was that had kept her trapped beneath those waters had been lifted with Bellatrix’s intrusion, her ritual carving out whatever stopper had held her captive.
