Draco was speaking casually of a future where Harry was a fixed point in his life - as if it were obvious that, once Voldemort was defeated, they would remain in one another’s orbit. He supposed it made sense; he doubted there was, or ever would be, anyone else on earth that he could relate too as much as Draco. His mind was drawn abruptly to the thick scar on his neck, and he felt sick with guilt. He needed to tell Draco - but how could he? If the choice was between killing Voldemort and saving Harry, he was becoming increasingly sure he knew which side of the fence Draco would fall on, and he couldn’t let that happen. It was more than Harry at stake here.
