I have to concur with lunabee34: that was my main issue with the epilogue as well (and, as I have already mentioned, the Battle of Hogwarts): I would have been all right with there not being a perfectly changed WW all of a sudden, since change takes time, but, as it was, the Trio seemed all of a sudden strangely complacent with the status quo, and that is not something I could believe of any of them.

Re Albus Potter's middle name: as you may have gathered from our last exchange so far, I am rather fond of (or better, rather interested in), Severus Snape, so I was initially rather pleased by this factoid. Looking back on it, I heartily agree with the criticism you make in your post. May I adopt your solution as my headcanon as well?
