Dudley ended up marrying a half-blood and had a daughter who could do magic.

One day Harry got a call from Dudley when he answered he was shocked at what he heard. "How do I stop my daughter from sneezing and burning the house down? Daisy don't touch that!" At this, Harry started to laugh a little. "You have magic kids' help!"

After this, Harry would go over and babysit for his cosine. Dudley apologized to Harry for being a git and told him that he thinks magic is really cool and he wishes he wasn't so mean to Harry when they were kids.

Harry forgave him and they became friends. Dudley's wife was a nice lady and became good friends with Ginny and wasn't bad on a broom.

Harry and Amelia would help little Daisy with her magic until she went to Hogwarts.
