Contemplating the task ahead would

Contemplating the task ahead would not make it easier or the water warmer. He stepped to the pool’s edge and placed Hermione’s wand on the ground still lit. Then, trying not to imagine how much colder he was about to become or how violently he would soon be shivering, he jumped.

Every pore of his body screamed in protest. The very air in his lungs seemed to freeze solid as he was submerged to his shoulders in the frozen water. He could hardly breathe: trembling so violently the water lapped over the edges of the pool, he felt for the blade with his numb feet. He only wanted to dive once.

Harry put off the moment of total submersion from second to second, gasping and shaking, until he told himself that it must be done, gathered all his courage, and dived.

The cold was agony: It attacked him like fire. His brain itself seemed to have frozen as he pushed through the dark water to the bottom and reached out, groping for the sword. His fingers closed around the hilt; he pulled it upward.

Then something closed tight around his neck. He thought of water weeds, though nothing had brushed him as he dived, and raised his hand to free himself. It was not weed: The chain of the Horcrux had tightened and was slowly constricting his windpipe.

Harry kicked out wildly, trying to push himself back to the surface, but merely propelled himself into the rocky side of the pool. Thrashing, suffocating, he scrabbled at the strangling chain, his frozen fingers unable to loosen it, and now little lights were popping inside his head, and he was going to drown, there was nothing left, nothing he could do, and the arms that closed around his chest were surely Death’s….

Choking and retching, soaking and colder than he had ever been in his life, he came to facedown in the snow. Somewhere, close by, another person was panting and coughing and staggering around, as she had come when the snake attacked….Yet it did not sound like her, not with those deep coughs, no judging by the weight of the footsteps….

Harry had no strength to lift his head and see his savior’s identity. All he could do was raise a shaking hand to his throat and feel the place where the locket had cut tightly into his flesh. It was gone. Someone had cut him free. Then a panting voice spoke from over his head.

“Are – you – mental?”

Nothing but the shock of hearing that voice could have given Harry the strength to get up. Shivering violently, he staggered to his feet. There before him stood Ron, fully dressed but drenched to the skin, his hair plastered to his face, the sword of Gryffindor in one hand and the Horcrux dangling from its broken chain in the other.

“Why the hell,” panted Ron, holding up the Horcrux, which swung backward and forward on its shortened chain in some parody of hypnosis, “didn’t you take the thing off before you dived?”

Harry could not answer. The silver doe was nothing, nothing compared with Ron’s reappearance; he could not believe it. Shuddering with cold, he caught up the pile of clothes still lying at the water’s edge and began to pull them on. As he dragged sweater after sweater over his head, Harry stared at Ron, half expecting him to have disappeared every time he lost sight of him, and yet he had to be real: He had just dived into the pool, he had saved Harry’s life.

“It was y-you?” Harry said at last, his teeth chattering, his voice weaker than usual due to his near-strangulation.

“Well, yeah,” said Ron, looking slightly confused.

“Y-you cast that doe?”

“What? No, of course not! I thought it was you doing it!”

“My Patronus is a stag.”

“Oh yeah. I thought it looked different. No antlers.”

Harry put Hagrid’s pouch back around his neck, pulled on a final sweater, stooped to pick up Hermione’s wand, and faced Ron again.

“How come you’re here?”

Apparently Ron had hoped that this point would come up later, if at all.

“Well, I’ve – you know – I’ve come back. If –” He cleared his throat. “You know. You still want me.”

There was a pause, in which the subject of Ron’s departure seemed to rise like a wall between them. Yet he was here. He had returned. He had just saved Harry’s life.

Ron looked down at his hands. He seemed momentarily surprised to see the things he was holding.

“Oh yeah, I got it out,” he said, rather unnecessarily, holding up the sword for Harry’s inspection. “That’s why you jumped in, right?”

“Yeah,” said Harry. “But I don’t understand. How did you get here? How did you find us?”

“Long story,” said Ron. “I’ve been looking for you for hours, it’s a big forest, isn’t it? And I was just thinking I’d have to go kip under a tree and wait for morning when I saw that dear coming and you following.”

“You didn’t see anyone else?”

“No,” said Ron. “I –”

But he hesitated, glancing at two trees growing close together some yards away.

“I did think I saw something move over there, but I was running to the pool at the time, because you’d gone in and you hadn’t come up, so I wasn’t going to make a detour to – hey!”

Harry was already hurrying to the place that Ron had indicated. The two oaks grew close together; there was a gap of only a few inches between the trunks at eye level, an ideal place to see but not be seen. The ground around the roots, however, was free of snow, and Harry could see no sign of footprints. He walked back to where Ron stood waiting, still holding the sword and the Horcrux.

“Anything there?” Ron asked.

“No,” said Harry.

“So how did the sword get in that pool?”

“Whoever cast the Patronus must have put it there.”

They both looked at the ornate silver sword, its rubied hilt glinting a little in the light from Hermione’s wand.

“You reckon this is the real one?” asked Ron.

“One way to find out, isn’t there?” said Harry.
