Allowing the line to be crossed with Augustus when he returned from his summons had been a terrible idea. Hermione's entire life seemed to be full of those. To give a person false hope about a future that could not be was cruel. Especially if she allowed herself to believe it too. No matter how many plans they made or promises they uttered, there wasn't a future with Augustus. At least not one that lasted long. An expiration date was always stamped onto their relationship. Just because they delayed it by over a decade didn't mean it wouldn't finally come calling.
