Snape let out a stream of mixed swear words and hexes, but with his wand ten feet away nothing happened.
“Wash out your mouth,” said James coldly. “Scourgify!”
Pink soap bubbles streamed from Snape’s mouth at once; the froth was covering his lips, making him gag, choking him—
“Leave him ALONE!”
James and Sirius looked round. James’s free hand immediately jumped to his hair.
It was one of the girls from the lake edge. She had thick, dark red hair that fell to her shoulders, and startlingly green almond-shaped eyes—Harry’s eyes.
Harry’s mother.
“All right, Evans?” said James, and the tone of his voice was suddenly pleasant, deeper, more mature.
“Leave him alone,” Lily repeated. She was looking at James with every sign of great dislike. “What’s he done to you?”
“Well,” said James, appearing to deliberate the point, “it’s more the fact that he exists, if you know what I mean…”
Many of the surrounding students laughed, Sirius and Wormtail included, but Lupin, still apparently intent on his book, didn’t, and nor did Lily.
“You think you’re funny,” she said coldly. “But you’re just an arrogant, bullying toerag, Potter. Leave him alone.”
“I will if you go out with me, Evans,” said James quickly. “Go on… go out with me and I’ll never lay a wand on old Snivelly again.”
Behind him, the Impediment Jinx was wearing off. Snape was beginning to inch towards his fallen wand, spitting out soapsuds as he crawled.
“I wouldn’t go out with you if it was a choice between you and the giant squid,” said Lily.
“Bad luck, Prongs,” said Sirius briskly, and turned back to Snape. “OI!”
But too late; Snape had directed his wand straight at James; there was a flash of light and a gash appeared on the side of James’s face, spattering his robes with blood. James whirled about: a second flash of light later, Snape was hanging upside-down in the air, his robes falling over his head to reveal skinny, pallid legs and a pair of greying underpants.
Many people in the small crowd cheered; Sirius, James and Wormtail roared with laughter.
Lily, whose furious expression had twitched for an instant as though she was going to smile, said, “Let him down!”
“Certainly,” said James and he jerked his wand upwards; Snape fell into a crumpled heap on the ground. Disentangling himself from his robes he got quickly to his feet, wand up, but Sirius said, “Petrificus Totalus!” and Snape keeled over again, rigid as a board.
“LEAVE HIM ALONE!” Lily shouted. She had her own wand out now. James and Sirius eyed it warily.
“Ah, Evans, don’t make me hex you,” said James earnestly.
