"Sirius left. We fought and he... He didn't understand, and I couldn't tell him
because Dumbledore―"
"Have you been drinking? Mia, whatever's wrong, I'm sure we can fix it."
"No." She shook her head. "It can't be fixed. It's all broken and I didn't fix it. Remus,
I'm so sorry. He'll never forgive me. How can he forgive me for not changing it all? For
not stopping Voldemort from k-k-k―"
Remus flinched at her open use of You-Know-Who's name, not because of his own
fears, but because it had become a habit picked up from the rest of society. "Mia, we've
talked about this. You know you can't change the future, and whatever happens is meant to
happen. We'll figure it out together, but no one is going to hate you, especially not Sirius.
Just give him some time to cool off and I'm sure it'll all work out."
Mia held up her left hand.
"What's that? Is... ?" His eyes widened and a cold chill ran through his entire body,
the feeling sinking into his heart. "Mia, is that what I think it is?"
She opened her palm to show the Time-Turner, with only a few grains of sand left
in the top portion.
"It's moving. It wasn't moving before," he said, swallowing down the panic that was
quickly rising in his chest. "Mia, when did it start moving?
"I'm guessing about nine months ago, but I only just found it."
"Why's it moving?"
"Because there can't be two of me," she explained. "Today's my birthday, Remus."
"Your birthday's in March," Remus corrected, shaking his head.
"Mia Potter's birthday is the twenty-seventh of March, but Hermione Granger
was—will be born on the nineteenth of September, 1979."
Remus held his breath. "What time?"
"One after ten," she whispered, a look of utter defeat in her eyes.
Remus pulled his pocket watch from his robes and clicked it open.
