While going back Soham's mind was full of thoughts for the first time ever.
He still remembers when he visited Orphanage for the first time. He was highly impressed by Harry's sister for showing such hard work for the orphanage.
Not a single penny was in black. It was all white clean to give the best to the orphanage kids. Not just that, every single kid in the orphanage was happy with their home provided by their Sister Serene.
Not just that time. Even when Harry proposed those plans made by his sister, he was highly surprised. Soham most of the time doubted his sister's actual age. A girl younger than them, could actually think what he thinks in the same manner.
Serene invested in their business a number of times too. Even though he has never seen her face he was very impressed by that girl. But he never thought Serene to be that girl.
