After Harry died, everyone forgot about Ron. Not just in the sense of random people on the stret not knowing the name of Harry Potter's best friend, but literally forgot.

Hermione, who hadn't missed his birthday in 9 years, never sent an owl. His mother and father rented out his bedroom. Even Pigwidgeon flew off to Ginny's home and never came back.

A somewhat pudgy boy about his age took Ron's hand and smiled. "You're part of London Below now," he said.

Ron squinted. "Have we met?"

"My name is Neville. You looked like you could a friend."

Ron smiled.
