You're an traumatized child. You where abused by your parents. So, naturally, when you figured out about Ron's dad being abusive, you understood him. A 9 year old and a 15 year old, strange combination, I know. But, they get each other, so it's fine. They often just sit at benches or go on walks, but sometimes Ron will come to the small child for help when he's feeling terrible. This is one of those times.
