Harry was still grinning, until the smile slowly slipped off his face. He looked utterly bemused. Ron was looking at me, too, shocked and conflicted. I could tell he wanted to know more, but didn't want to speak to me for fear of being humiliated. I have that kind of an effect on people.

"But…what do you mean?" Harry asked. I took a deep breath.

"It means I'm your sister."

"Sister?" repeated Harry.

"You know, sister? Daughter of your parents, James and Lily Potter?"

"But—Hagrid just told me about my-our parents; he never said anything about a sister."

"Well, apparently, I'm the forgotten child." I grinned.

"How could they forget you?" piped up Ron. We both looked at him.

"I know I'm incredibly charming and magnificent, but technically, you could say I'm not supposed to be alive." Ron yelped and jumped back.

"Are you a ghost? Inferi?" He scrambled away.

"Don't be a dunce," I said calmly. I started to explain what Grandmother had told me yesterday, about my parents and Dumbledore and St. Mungo's. Harry's face kept getting more and more confused, and Ron's more and more excited.

"So you're like a half-person?" Ron asked. I looked at him scathingly.

"Do you see me right now?" I asked.

"Yes."

"Do I have the same amount of limbs as you do?"

"Yeah, I guess."

"Do I look like any other animal?"

"No, not really."

"Then what do you think?"

"You're not…part-human?"

"Wow." I said, slowly clapping my hands. "You. Are. A. Genius." Ron blushed again. "Anyway, at least I'm not all weasel." Aw, I was pretty harsh on the kid. But hey! That's what you get for insulting Olivia Polack!

"Have you seen Trevor? He's a toad and I've lost him!" a round-faced boy popped his head into the compartment. We shook our heads no. "Grandmother's going to kill me!" he wailed. I can sympathize with that. He hurried away.

"I still don't get it." Said Harry, looking out the window.

"Trust me, it's pretty new to me, too. I just found out yesterday. My whole life I thought I was a Black. That's why I said Polack. It's a mixture of Potter and Black."

"No, that's not really it. How could you know about the wizard world and I didn't? You're younger than me!"

"Only by a few months." I reminded him. "Helping me survive takes around a year of your life." I frowned. "That's kind of ironic, actually."

"But how did you know?" persisted Harry.

"Grandmother told me." I said simply.

"Our grandmother's alive? But I thought everyone in my family was dead! And then I find out I have a sister and a grandmother!" Harry said.

"Well, you had a grandmother anyway, alive or dead." I pointed out.

"Alive grandmother!" He corrected himself. "Why couldn't I live with you guys then?"

"Don't you remember what I said earlier, when you asked me why I didn't fawn over you? Same reason. You would have had an extremely ginormous head. I shudder what would happen if people would think we're related then!"

"Speaking of which, we don't look at all alike." Harry looked at me and I looked at him. It was true: He has bright green eyes and black hair, I have red-orange hair and hazel eyes. He has skinny legs and knobby knees, while I have long, muscly legs from playing Quidditch so much. I have high cheekbones and freckles, he doesn't. He obviously doesn't have a temper, and I do. Maybe it's a redhead thing. But anyway, the only thing we have in common is our slight build.

"I guess you're right. But from the pictures I've seen of our parents, you look like our dad and I look like our mom. I have Dad's eyes, though, and you have Mom's eyes. So it's kind of like a switcheroo."

"You have pictures of our parents? Do you have them with you?" Harry asked eagerly.

"Not with me, sorry no." I said apologetically. Harry looked disappointed.

"So, what were they like?"

"I have no idea. I only knew I was a Potter since yesterday, and after we argued about yo—something, we didn't really talk much."

"Who are you?" Ron was asking. I looked at him. I was about to say that I don't remember learning that weasels have extreme amnesia, when I saw him talking to a girl in the doorway while holding his rat and his wand.

"Have you seen a toad?" she asked, ignoring him, while tossing her bushy brown hair importantly, "Neville's lost his."

"No, he's just been here. Who are you?"

"I'm Hermione, Hermione Granger."
