Harry didn't think he needed Lupin.
No, he didn't think he did.
He was sure he needed him. Harry was sure he needed him, every time he sat looking about Sirius's lonely house ; as the cold nearly swallowed him whole.
Every time Lupin looked at him and smiled , Harry knew, that he was all he would never need , now.
He didn't need Dumbledore to tell him , it was wrong, when His arms wrapped around Lupin's warm body.
Or when Lupin patted his knee, secretly under the table.
He didn't need anyone to say anything.
Because if they were him , they would surely understand.
He just knew.
He just knew.
