That distracted him sufficiently. “Harry Potter…is my half-brother.” He said slowly, the words foreign and thick on his tongue. “But I hate him!”
The world shimmered and wavered in front of him, and he swayed. The last thing he heard was his mother saying distantly, “Rest, Draco. It is much to take in. I will send word to Severus that you came home early due to illness. We will speak more tomorrow,” before he was enveloped in darkness.
The next morning, Draco joined Narcissa at the breakfast table as usual. He looked perfectly normal, not a hair out of place, clothes neatly pressed and tucked as bespoke a true English wizard of the old blood. Dolly, their new house elf, quietly filled their plates and disappeared with a soft pop! , leaving mother and son alone.
“So.” Draco began, the opening gauntlet. “What happens now?”
She eyed him warily.
“Harry Potter hates me, and I hate him. You haven’t done a very good job on that vow of yours, by the way. The idiot has nearly gotten himself killed at least three times for every year he’s been at Hogwarts. And those were just during the Quidditch matches.”
She was bemused at the calm, accepting, matter of fact attitude, but not truly surprised. Within all the pureblood families was a blood géis of varying strength, to remain loyal to each other no matter what. As the Black and Potter families, and especially Draco and Harry, were so closely related, it ran stronger in their blood, especially now that at least one side had acknowledged the relation. The blood géis was meant to prevent patricide when heirs or siblings got greedy for their inheritance, but it worked for half siblings too. It also helped that the bracelet with the loyalty rune on it was gone, and with it the nullifying effect; though now with nothing to stem it, the blood géis was flowing stronger than ever, like a river that had just broke through a dam.
“I know that there is a schoolyard animosity between you and Harry. Part of that is your shared history working against you; you are much alike, in a lot of ways.” She replied, setting her tea cup down and accepting that this conversation needed to happen before either of them were to take another bite. “Part of that, Draco my darling, is you not being at all subtle or cunning, but that is Lucius’s influence. From what you have told me, it is petty resentments and teenage grudges that make up the majority of your feud, as well as the long standing dislike between Slytherin and Gryffindor House.”
“Yes.” He agreed grudgingly. “Although it is more Weasel and Granger that are always up in arms. Weasley had already gotten to Potter before we even entered Hogwarts the first time, spouting off his nonsense about evil Slytherin and goody two-shoes Gryffindor. Potter ate it up.”
“I suspect that there is much more Slytherin in Harry than anyone realizes.” Narcissa mused thoughtfully. “His mother Lily was certainly the most cunning and Slytherin like Gryffindor I’ve ever met in my life.” She smiled fondly, reminiscing. “Though I didn’t realize exactly quite how much she had successfully manipulated everyone until long after we were out of school. But then, she was a politician’s daughter, and a Muggle born. She was used to hiding in plain sight.”
