Can I jump in on this?

I really don't understand the problem with the names in the epilogue. Sure, they kind of sound like bad fanfic names, but so do most of the names in the series! Within the context of Rowling's literal (not really the best word, but you get the idea) universe, I think it makes perfect sense.

So, yes, Albus Severus Potter is an exceptionally silly name. But Harry would totally name his kid that.
