The coordination with Ron and Hermione was as easy as breathing. The link between them wide open. What had been irritating before, was now easy and comfortable, because the trio shared a common goal: protecting each other while defeating the enemy. Of course, the teenagers knew that they could not seriously harm their opponent. Still, creative use of Wingardium Leviosa and Levicorpus gave them an edge; mostly because they were three against one. Lord Voldemort did not seem to have any scruple. He cast fire and ice, cut up fabric and tore apart furniture when the teenagers jumped out of the way of his spells. For what felt like hours, they duelled until Tom had them cornered, hiding behind overlapping shield spells, maintained by the last of their strength.
