- I can't reveal much without exposing my plot... But consider the power of a head of house...
Yes, I figured something along those lines. I rather expect things to be improved once certain friends get to talk with Harry and Daphne; I don't expect her father is going to enjoy the repercussions, either, as there are so many non-violent ways Harry can cause him great pain with the power that Harry does have at his disposal. I rather figure this is going to end up being an education for Harry in how to use his position/titles/money/etc.
In the longer term, I can't seem them getting immediately back together, but I can see them still being very good friends and possibly dating others to get a better appreciation for how they feel for each other.
