Fresh Bait
Harry stared at the letter. Her name was Ginny. That was the same girl from yesterday. So he did know her. But how was that possible? He didn't remember her at all.
Flashback
Harry was sitting on the cushion facing Monsieur. He had been in France for a little over a month, and this is what he did everyday.
"Concentrate, Élève." Monsieur said, a little frustrated. Harry was a hard student to teach.
"I'm trying, Monsieur," Harry said irritably. "If only I had my wand back…"
"No wand!"
Harry grumbled some more. The second day he'd been in France, Monsieur had taken away his wand, his broomstick, his invisibility cloak, and all things magical. Monsieur had said that if he wanted to learn to do wandless magic, then he needed to live without a wand for a while. There was a considerable amount of arguing on Harry's part about that, but Monsieur took his magical items anyway.
Harry closed his eyes and tried to block out Monsieur, who kept on going into his mind with no apparent difficulty. He saw Ginny over and over again in his head.
"Who is that girl, Élève?" Monsieur suddenly asked.
"Oh, that's nobody…" But even as he said it, a picture of Ginny swam around Harry's mind.
"Oh, someone you care about?" It looked like Monsieur was smiling.
"Er…"
There was a moment of awkward silence between the student and the teacher, before Harry suddenly felt a blinding pain on his forehead.
"Aaaaargh!" Harry clutched his hand over his scar as a picture of Ginny danced around his head. She looked like she was screaming in agony, as if an invisible force was attacking her.
What's happening to her?
Protect her, Élève. That was Monsieur's voice in Harry's head. Harry looked at Monsieur, who had his eyes closed. He understood. This wasn't happening in real life. Monsieur had just finally found a bait to make Harry concentrate.
Harry knew it was just an illusion, but Ginny looked like she was in so much pain…
Leave her alone…
You must fight to protect her, Élève.
Harry closed his eyes tight, and tried to imagine himself acting as a barrier between Ginny and the invisible foe.
Harry felt another blinding pain on his forehead. But he wasn't hurt as badly as Monsieur. Harry opened his eyes to find Monsieur at the other side of the room, sprawled against the wall as if he had been violently thrown there.
"Élève," Monsieur said, breathing heavily. "I've never… I've never seen that much force for just a beginning student…"
"Are you alright, Monsieur?" Harry asked, feeling slightly guilty.
"Oh, I'm fine, Élève." Monsieur huffed some more. "Just go get some rest."
As Harry stood up to leave, he had a slight suspicion that Monsieur – who was now lying on two cushions that were placed side by side – needed more rest than he did.
