This chapter was awesome it cleared up loose ends and really justified a lot of things Harry had been working towards. The circumstances with Ron were a long time overdue, and it's not done yet. He has been jealous of Harry for a long time, being disowned and basically cast aside by the side if light will just bring it to a head. Harry has not heard the last of him.
As to the choice of mothers for the boys children I'm not surprised at all, I've silently been rooting for Hermoine for a while and Ginny is another excellent choice.
Love the way the story is shaping up!!!!!
