They arrived at Harry's building a week after the original plan — one day later than that, because they'd stayed up too late watching a second film and Hermione hadn't been able to sleep and Kevin's bed had been where she'd ended up, and neither of them had been in any particular hurry to change the arrangement.
Dobby opened the front door before they'd finished knocking, bowing so enthusiastically that his pillowcase hat slipped sideways.
"Welcome! Great wizards, welcome!"
"Dobby. Good to see you." Kevin handed over the owl cage. "You're charging eight Galleons?"
"Yes! But Dobby only needs one —"
"Charge ten," Kevin said. "You're worth it."
"Kevin, I am right here," Harry's voice came from the end of the hall.
"Then you heard me," Kevin said, walking in.
Sirius emerged from the lounge. "Kevin! Hermione! We thought something had happened."
"We took a day," Kevin said.
"A day," Sirius repeated, looking at the two of them with the expression of a man assembling information. "Right. Top floor, both of you. Harry's put you in the end units."
Hermione, very pink, carried her own bag up the stairs.
That night, Kevin ended up in the large top-floor room with Harry and Ron. The bed was big enough for three without difficulty, which didn't stop Ron from complaining about the arrangement.
Ron's snoring started approximately eleven minutes after lights-out.
Kevin muffled it wandlessly. Harry felt the shift in the air and sent a silent thumbs-up into the dark.
"You're not asleep," Harry said.
"Asleep," Kevin said.
A pause.
"I want to actually talk. This is important."
"Then tell Sirius."
"...Can you just listen first?"
Kevin said nothing, which Harry correctly interpreted as agreement.
"I've been having the same nightmare for weeks," Harry said. "Every time. I see Peter Pettigrew grovelling on a floor, mumbling things I can't quite hear. There's a shadowy figure beside him — I can't see the face. And there's a large snake nearby."
He paused.
"And I always wake up with my scar hurting."
Soul fragment resonance. Voldemort's piece in Harry, picking up signal from Voldemort's piece in Voldemort. The connection running both ways.
"In the dream," Kevin said, "do you know who you are? Or does it feel like you're seeing through someone else's eyes?"
Harry went very still.
"Someone else's," he said, after a moment.
"Tell Sirius," Kevin said. "First thing tomorrow. Not next week. Tomorrow."
"It feels paranoid. He's only just got settled —"
"Harry." Kevin turned his head slightly. "You've been carrying a dead man's soul fragment in your head since you were a year old. A nightmare that makes your scar hurt is not paranoia. Tell Sirius. That's what he's there for."
A long silence.
"Yeah," Harry said. "Okay."
Another silence.
"Kevin," Harry said. "What's a Makka Pakka?"
"Go to sleep."
"You've said it twice now. What is it?"
"It is a small creature that tidies things in the night and has no relevance to your current situation."
"That's a very specific answer."
"Good night, Harry."
