Snape reacted so fast it was as though he had been expecting an attack: dropping his bag, he plunged his hand inside his robes and his wand was halfway into the air when James shouted, 'Expelliarmus!'
Snape's wand flew twelve feet into the air and fell with a little thud in the grass behind him. Sirius let out a bark of laughter.
'Impedimenta!' he said, pointing his wand at Snape, who was knocked off his feet halfway through a dive towards his own fallen wand.
Первое заклинание - Джеймс, второе - Сириус.

Но да, вы правы, это уже флуд пошел :)
