“It was a ball of light, kind of pulsing, and bluish, like that light you get around a Portkey, you know?”

“Yeah,” said Harry and Hermione together automatically.

“I knew this was it,” said Ron. “I grabbed my stuff and packed it, then I put on my rucksack and went out into the garden.

“The little ball of light was hovering there, waiting for me, and when I came out it bobbed along a bit and I followed it behind the shed and then it . . . well, it went inside me.”

“Sorry?” said Harry, sure he had not heard correctly.

“It sort of floated toward me,” said Ron, illustrating the movement with his free index finger, “right to my chest, and then — it just went straight through. It was here,” he touched a point close to his heart, “I could feel it, it was hot. And once it was inside me I knew what I was supposed to do, I knew it would take me where I needed to go.”

“The Deluminator?” she asked, so surprised she forgot to look cold and fierce.

“It doesn’t just turn the lights on and off,” said Ron. “I don’t know how it works or why it happened then and not any other time, because I’ve been wanting to come back ever since I left. But I was listening to the radio really early on Christmas morning and I heard . . . I heard you.”

He was looking at Hermione.

“You heard me on the radio?” she asked incredulously.

“No, I heard you coming out of my pocket. Your voice,” he held up the Deluminator again, “came out of this.”

“And what exactly did I say?” asked Hermione, her tone somewhere between skepticism and curiosity.

“My name. ‘Ron.'”

“Hermione!”

She stirred, then sat up quickly, pushing her hair out of her face.

“What’s wrong? Harry? Are you all right?”

“It’s okay, everything’s fine. More than fine. I’m great. There’s someone here.”

“What do you mean? Who — ?”

She saw Ron, who stood their holding the sword and dripping onto the threadbare carpet. Harry backed into a shadowy corner, slipped off Ron’s rucksack, and attempted to blend in with the canvas.

Hermione slid off her bunk and moved like a sleepwalker toward Ron, her eyes upon his pale face. She stopped right in front of him, her lips slightly parted, her eyes wide. Ron gave a weak, hopeful smile and half raised his arms.

Hermione launched herself forward and started punching every inc of him that she could reach.

“Ouch — ow — gerroff! What the — ? Hermione — OW!”

“You — complete — arse— Ronald — Weasley!”

She punctuated every word with a blow: Ron backed away, shielding his head as Hermione advanced.

“You — crawl — back — here — after — weeks — and — weeks — oh, where’s my wand?”

“After you left,” he said in a low voice, grateful for the fact that Ron’s face was hidden, “she cried for a week. Probably longer, only she didn’t want me to see. There were loads of nights when we never even spoke to each other. With you gone . . .”

He could not finish; it was only now that Ron was here again that Harry fully realized how much his absence had cost them. 

“She’s like my sister,” he went on. “I love her like a sister and I reckon she feels the same way about me. It’s always been like that. I thought you knew.”

Ron did not respond, but turned his face away from Harry and wiped his nose on his sleeve. Harry got to his feet again and walked to where Ron’s rucksack lay yards away, discarded as Ron had run toward the pool to save Harry from drowning. He hoisted it onto his own back and walked to Ron, who clambered to his feet as Harry approached, eyes bloodshot but otherwise composed. 

“I’m sorry,” he said in a thick voice. “I’m sorry I left. I know I was a — a —”

He looked around at the darkness, as if hoping a bad enough word would swoop down upon him and claim him. 

“You’ve sort of made up for it tonight,” said Harry. “Getting the sword. Finishing off the Horcrux. Saving my life.”

“That makes me sound a lot cooler than I was,” Ron mumbled. 

“Stuff like that always sounds cooler than it really was,” said Harry. “I’ve been trying to tell you that for years.”

Simultaneously they walked forward and hugged, Harry gripping the still-sopping back of Ron’s jacket. 

“So, have you got it?” Harry asked her, partly to remind her that he was there.
“Got — got what?” she said with a little start.
“What did we just go through all that for? The locket! Where’s the locket?”
“You got it?” shouted Ron, raising himself a little higher on his pillows. “No one tells me anything! Blimey, you could have mentioned it!”

“Snape, headmaster! Snape in Dumbledore’s study — Merlin’s pants!” she shrieked, making both Harry and Ron jump. She leapt up from the table and hurtled from the room, shouting as she went, “I’ll be back in a minute!”
“‘Merlin’s pants’?” repeated Ron, looking amused. “She must be upset.” He pulled the newspaper toward him and perused the article about Snape.
…
“Oh, here she is,” Ron added, craning around in his seat to watch Hermione reentering the kitchen. “And what in the name of Merlin’s most baggy Y Fronts was that about?”
