This was by far one of the worst days in his life. While the rest of the wizarding world was celebrating the downfall of He-Who-Must-Not-Be-Named, Remus Lupin was at his place feeling shattered.
Never did he imagine he'd lose someone so close to him. Obviously the first Wizarding was a living nightmare to the magical folks and him along with his friends wanted to fight the Dark Lord by joining the Order of the Phoenix.
They've suffered many losses in the past three years but not one had hit him as hard as the loss of his bestfriends Lily and James Potter.
They were one of the most caring and loving people he'd met and they deserved to be happy. But all that was stripped away from them and especially their two children who now were orphans thanks to Lord Voldermort.
He was devastated.
So he sat there in his living room mourning the death of Lily and James Potter until a sharp knock on his front door startled him. It was around 3 am on the morning of the 1st of October, so he wondered who'd be visiting him in the middle of the night.
'Must be Sirius or Peter!' he thought.
But it wasn't either of his friends because once he flunged the door open a little girl jumped into his arms and started sobbing.
His visitors were the last people he wanted to see but seems like Dumbledore had other plans. The little girl was none other his god daughter Natalie Potter, the eldest daughter of his recently murdered bestfriends.
She was escorted by Prof. McGonagall, the transfiguration teacher at Hogwarts school of Witchcraft and Wizardry.
Holding Nat tightly in his arms he looked at Prof. McGonagall who seemed to be holding back tears of her own. She gave him a stiff nod and said "Mr. Lupin, Dumbledore told me to inform you that you are Natalie only remaining Guardian. So please do look after her."
Soon she had a few tears streaming down her face. Chocking back a sob she then proceeded to tell him "Oh and Send her to the Weasley's during full moons. I'm sure they'd be glad to take care of her when you can't."
With that she turned around and dissapperated but not without turning back at Natalie one last time.
That was the night Remus Lupin's life changed when he took in three year old Natalie Lily Potter under his wing.
He swore he'd never let anything happen to her again because the young girl has already been through so much.
