This question stopped Hermione in her tracks. She wasn’t sure what cataclysmic change had occurred within their time together. It wasn’t an obvious shift at first. It was small cracks in a dam, nothing to worry about. Until one too many fissures spread, and then it was as if everything was compromised. Incomprehensible damage would occur, surely, once the dam broke. And it was nearly there, with water spurting through, cleaving off more and more of the levee until nothing was left to hold back the surge.
