On the edge of a sob, she pleaded, "Please send me back. Always send me back.
Remus, don't take my life away from me. Don't take him away from me."
Remus could only think she meant Sirius, and he understood. It was up to him to
send a nineteen-year-old girl thirty years into the past just so she could fall in love with
Sirius Black—and himself at a certain point, but that was neither here nor there any
longer. Sirius was the important part now. She needed Sirius, and Sirius definitely needed
Mia. Remus was getting exhausted trying to take care of them both.
"It took so much to get him back," she whispered. "He lost too much, Remus. I
didn't even do it for me, you know? At least I didn't think so at the time. I just... I thought
of him when I saw the spell in that book, and I thought... Harry needs him, and maybe I
could give that to him."
Though he had not a clue as to what Mia was talking about, he continued to stroke
her hair, using his wand to clean up the broken glass everywhere before he sat down and
pulled her up against him. He took the bottle from her hand and set it down next to him.
"Tell me about Harry."
"I can't." She sulked. "You know I can't."
"You can tell me about him because you're not going to change anything," he
explained. "That's how it works, right?"
After a long moment of silence, Mia whispered, "I miss him. He was my best
friend."
Remus smirked, pressing his lips to the top of her head. "I'm hurt. I didn't realise I
was so easily replaceable."
"You're my best friend too," she said, poking her finger into his chest.
"So what made Harry different? How'd you meet?"
"On the train. Broken glasses, Potter hair, and the brightest green eyes I'd ever seen."
"Lily's eyes," Remus whispered with a smile.
Mia let out a soft, teary laugh. "It was so funny. He was there with Ron―"
"Who's Ron?"
"You'll see," she said, waving off the question. "Anyway, Ron was trying to do magic
to show off. Said this worthless spell over his r-r-r... Scab-b-b—Fuck!"
