Two Killing Curses shot toward Ron and Ginny almost simultaneously.
At almost the same moment, light gathered again in the thundercloud overhead, clearly heralding another lightning strike. Ginny was still locked in a contest with Dolohov and could not spare a hand, while Ron had to maintain the Patronus Charm. For a moment, the situation was rather dangerous.
But Dolohov was not alone, and Ron and Ginny were not the only two on their side, either.
A figure shot out of the blue flames that had previously shrunk into a ball. He soared into the air, wings unfurling behind him with a swish. It was Harry, of course.
The wings had been transformed from his coat. This particular piece of Transfiguration was one of Professor McGonagall's specialties, and since Harry and Ron were students she liked very much, she naturally held nothing back when teaching them.
Professor McGonagall had taught the two of them this technique back during the Magic Cup Triwizard Tournament. They had tried it, but their control had not been very good, so they had not used it.
Still, both Harry and Ron thought the move looked very cool, so they had practiced it in private. By now, Harry could control it quite well. He shot skyward, then used the transformed wings to hover in the air.
Even after he left it, the Fireshield Charm below remained, and he could still control it. Two jets of blue flame shot out, blocking the other two Death Eaters' Killing Curses.
At the same time, he pointed his wand at the sky. "Expecto Patronum!"
Amid dazzling silver light, a majestic male lion surged out faster than flight and plunged headfirst into the dark clouds overhead.
In just a few breaths, it tore the thundercloud apart, smothering the two lightning bolts
