He could only see a sliver of Sirius’s face; the rest was in darkness.
“It must have been the aftermath of the vision, that’s all,” said Sirius. “You were still thinking of the dream or whatever it was and—”
“It wasn’t that,” said Harry, shaking his head, “it was like something rose up inside me, like there’s a snake inside me.”
“You need to sleep,” said Sirius firmly. “You’re going to have breakfast, then go upstairs to bed, and after lunch you can go and see Arthur with the others. You’re in shock, Harry; you’re blaming yourself for something you only witnessed, and it’s lucky you did witness it or Arthur might have died. Just stop worrying.”
He clapped Harry on the shoulder and left the pantry, leaving Harry standing alone in the dark.

Everyone but Harry spent the rest of the morning sleeping. He went up to the bedroom he and Ron had shared over the last few weeks of summer, but while Ron crawled into bed and was asleep within minutes, Harry sat fully clothed, hunched against the cold metal bars of the bedstead, keeping himself deliberately uncomfortable, determined not to fall into a doze, terrified that he might become the serpent again in his sleep and wake to find that he had attacked Ron, or else slithered through the house after one of the others…
When Ron woke up, Harry pretended to have enjoyed a refreshing nap too. Their trunks arrived from Hogwarts while they were eating lunch, so they could dress as Muggles for the trip to St. Mungo’s. Everybody except Harry was riotously happy and talkative as they changed out of their robes into jeans and sweatshirts. When Tonks and Mad-Eye turned up to escort them across London, they greeted them gleefully, laughing at the bowler hat Mad-Eye was wearing at an angle to conceal his magical eye and assuring him, truthfully, that Tonks, whose hair was short and bright pink again, would attract far less attention on the Underground.
