Harry James Potter has been a lot of things in his life, most of them born of necessity.
He was small and fast in childhood, smart and lucky during his years at Hogwarts, selfless and brave during the war. After the war, when his responsibilities were over, he became quiet and reflective, beholden to no one.
As a father, he was strong and loving. His whole life had been a heavy responsibility, but he’d never expected the weight that three young lives would place on his shoulders. He is still all of things he’s always been, though he can feel obligation down to his bone marrow.
It isn’t until he’s a grandfather - until a grinning James hands him little Lee Winter Potter, minutes old and so warm and sleepy and sweet that Harry finds within himself softness.
There’s no crushing weight of destiny and blame upon him this time, it’s just him and his tiny grandson, seemingly alone in the world. Ginny falls in love with him over again, and James vows to see that look on his father’s face as much as humanly possible in the coming years.
Harry is as close to his first grandson as he’s ever been to anyone. His affection and love for him even rivals how he’d felt about Ron and Hermione in their younger, desperate days.
He finds, in Lee, peace.
For the anon who asked about “lovely, sweet, grandpa Harry” - here it is :)
