"And this tradition is just accepted that easily?" Harry asked, ignoring the insults.
"Even by pureblood families like yours?"
"Yes," Draco affirmed. "In fact, my mother told me that when she was having
trouble getting pregnant with me, she'd suggested magical adoption just to be able to
provide an heir for my father to fulfil her marital vows. But by then Father was too caught
up in the Dark Lord's plans."
"Why would that have mattered?" Harry questioned.
"Because the Dark Lord didn't approve of magical adoption," Draco replied.
Ron frowned. "I still don't get it. If magical adoption would turn any Muggle-born
or half-blood into a pureblood, then why was he against it?"
Draco raised an incredulous eyebrow. "Because, unlike the rest of the Wizarding
world, the Dark Lord actually did see it as a blood status thing and not just magical purity.
Neither of which make a difference now, of course."
Harry dipped his head, finally understanding. "It makes sense. Tom Riddle was an
orphan."
"And would you like to be the person to tell a sociopathic tyrant that all his problems
would have been solved if some pureblood family loved him enough to give him their
name?"
Harry looked to Remus. "Does this mean anything for Hermione? Being a
pureblood now?"
Remus scratched his chin thoughtfully. "I'm not sure," he answered. "We knew that
Mia was adopted, of course, but we never really gave much thought to her Muggle-born
status or the state of her magical signature. And Hermione has always been a proud
Muggle-born; I imagine she'll be very open about both of her parentages. By all laws, she
is a Potter, so she'll have access to the vaults and properties."
"Black vaults and properties as well," Sirius chimed in. "Her mother was a Black."
"I didn't even make that connection," Draco grimaced. "I'm related to Hermione
Granger. Does she still have the Time-Turner? I'd love to go back to third year and tell my
thirteen-year-old self just to see the look on my face."
"It'd probably look just as stupid as it does now," Ron remarked.
"Behave, Ronald."
