TomAndJerrySaidSo wants James Sr + Mini!Harry, and "Unconditional Love".
He knew, knew oh so well, that he wasn't his. It was obvious, really. She'd done a rather shabby job of disguising him, and an even shabbier job of researching Potter Family History.
His eyes were green. That was her biggest mistake. No Potter male had green eyes. No Potter period had green eyes. Something in the genes, in the Family magic, made it impossible. All Potters had, since the beginning of records, had hazel eyes.
The curse of the Potters, it was called. Almost carbon copies of their fathers, and their fathers before them. They always take after their father. That was her biggest mistake: she made his eyes like hers.
She'd done good research, but not good enough. Potters always have one prominent trait, inherited from their mother. But not the eyes, never the eyes.
He did not know who the father was - maybe she didn't either.
But one thing he did know.
James Potter would always love Harry Potter unconditionally, no matter his heritage.
As shown in this chapter: if you want two characters to star in your drabble, but not be paired, write it like character + character. Good? Good.
