Harry/Hermione: Fireside 

He forced down some dinner after Divination, then returned to the empty classroom with Hermione, using the Invisibility Cloak to avoid the teachers. They kept practicing until past midnight. They would have stayed longer, but Peeves turned up and, pretending to think that Harry wanted things thrown at him, started chucking chairs across the room. Harry and Hermione left in a hurry before the noise attracted Filch, and went back to the Gryffindor common room, which was now mercifully empty. 

At two o’clock in the morning, Harry stood near the fireplace, surrounded by heaps of objects: books, quills, several upturned chairs, an old set of Gobstones, and Neville’s toad, Trevor. Only in the last hour had Harry really got the hang of the Summoning Charm. 

“That’s better, Harry, that’s loads better,” Hermione said, looking exhausted but very pleased. - The First Task, Goblet of Fire
