The Doctor looked over himself. "Since you didn't recognize any of us, you don't have my memories, rather odd that, what's that stick in your hand?" Without waiting for an answer, he whipped out his sonic, and sonic-ed the stick. He frowned and shook his head. "Wood. Of course. I really need to invent a setting for that. This is getting embarrassing." He finally realized he was ignoring the man in front of him. "So, what's your name? And why are you here?"

The man, who the Doctor noticed had kept his stick pointed at him the entire time, shook his head. "Show me your arm first. All of you!" The bewildered Doctor and Ponds pulled up their sleeves, revealing bare skin. He lowered his stick. "Sorry about that. Had to make sure you weren't Death Eaters. I'm Harry Potter." He waited for the expected gasps of recognition, frowning at their lack of reaction. Suddenly it hit him what the man in front of him had said his name was. "Wait. You said your name was the Doctor."

The Doctor smiled. "Yep. That's me. What seems to be the problem?"

Harry frowned. "If you're the Doctor, then that means… you're an alien!" he scampered backward from the Doctor, raising his wand. He took a glance at the bewildered Ponds, "And what are they, they're aliens too, aren't they?"

"Whoa, whoa, whoa." interjected Amy. "Completely normal humans here, and don't worry about the Doctor, he's harmless."

"Oi!" said the Doctor. "I resent that." still glaring at Amy, he turned to Harry. "So, what were we doing here again?"

Harry, rather confused by the dialogue between the two, managed to work out "Uh… I'm here to kill Voldemort?"

The Doctor approached Harry. "And what has he done that's so bad? I'm rather against killing you know."

"He's a racist murderer, he killed my parents, my godfather, has attempted to kill me several times, he's my nemesis, do I need any other reason?" Harry snarled. "You have no idea what I've gone through at the hands of this lunatic!"

The Doctor gave a bitter laugh. "I know exactly what you've gone through. I have my own nemesis, they've destroyed everything important to me. It's because of them that I am completely alone. And that's why I'm going to help you. What's the plan?"

Harry, rather surprised by the outburst, chuckled nervously. "Well, there really wasn't one, I was just going to walk in and start throwing curses." He wrung his hands, ignoring their incredulous looks. Finally he broke. "Well do you have a better idea?" he demanded.

The Doctor smiled at the Ponds. "Actually I do. Let's go!" and with that, he marched through the front gate.

Harry looked at the Ponds. "Is he always like this?"

Amy smiled. "Yep. Wouldn't have him any other way. Now let's go! We're falling behind!" Amy and Rory jogged up to keep pace with the Doctor.

Harry sighed. "I've joined a bunch of loonies." Finally deciding he didn't have a better option, he sprinted to catch up with the others.
