Mine, Harry's, and Ron's last exam was Divination; Hermione's, Muggle Studies. We walked up the marble staircase together. Hermione left us on the first floor, and Harry, Ron, and I proceeded all the way up to the seventh, where many of our class were sitting on the spiral staircase to Professor Trelawney's classroom, trying to cram in a bit of last minute revision.

"She's seeing us all separately," Neville informed us, as we went to sit down next to him. He had his copy of Unfogging the Future open on his lap at the pages devoted to crystal gazing. "Have any of you ever seen anything in a crystal ball?" he asked us unhappily.
"Nope," said Ron, in an offhand voice. He kept checking his watch; I knew he was counting down the time until Buckbeak's appeal started.

The queue of people outside the classroom shortened very slowly. As each person climbed down the silver ladder, the rest of the class hissed, "What did she ask? Was it ok?"
But they all refused to say.
"She says the crystal ball's told her that if I tell you, I'll have a horrible accident!" squeaked Neville, as he clambered back down the ladder towards Harry, Ron, and me. We'd now finally reached the landing after what had seemed to be an age of waiting.
"That's convenient," snorted Ron. "You know, I'm beginning to think Hermione was right about her—" he jabbed his thumb towards the trapdoor overhead "—she's a right old fraud."
"Yeah," said Harry, checking his watch.
"What's the time?" I asked him.
"Two o'clock," he said. "Wish she'd hurry up..."

Parvati came back down the ladder, glowing with pride.
"She says I've got all the makings of a true Seer," she informed us. "I saw loads of stuff... well, good luck!"
She hurried off down the spiral staircase towards Lavender.

"Ronald Weasley," said the familiar, misty voice from over our heads.
Ron grimaced at us, then climbed the silver ladder out of sight. Harry and I were now the only people to be tested. There was no way either of us was going to do well at it, same with Ron; our minds were elsewhere. Harry and Ron were both worrying about Hagrid and the appeal, and I was still thinking about my Boggart earlier.

Finally, after about twenty minutes, Ron's large feet reappeared on the ladder.
"How'd it go?" Harry asked him as I stood up.
"Rubbish," said Ron. "Couldn't see a thing, so I made some stuff up. Don't think she was convinced, though... I'll see you two in the common room, yeah?"
"I'll probably be a bit later than Harry," I said. "I've got to go see Lupin first."
"Good luck," Harry muttered to me as Professor Trelawney's voice called, "Ivory Riddle!"

The tower room was hotter than ever before; the curtains were closed, the fire was alight, and the usual sickly scent made me cough as I stumbled through the clutter of chairs and tables to where Professor Trelawney sat waiting for me before a large crystal ball.
"Good day, my dear," she said softly. "If you would kindly gaze into the Orb... take your time, now... then tell me what you see within it..."

I bent over the crystal ball and stared, stared as hard as I could, willing it to show me something other than swirling white fog, but nothing happened.
"Well?" Professor Trelawney prompted delicately. "What do you see?"
The heat was overpowering, and my nostrils were stinging with the perfumed smoke wafting from the fire beside us. I thought of what Ron had just said, and decided to pretend.

"Er—" I said, "—a dark shape... um..."
"What does it resemble?" whispered Professor Trelawney. "Think, now..."
"A girl," I said. It'd been the first thing that popped into my head. "A young girl... um... lying on the floor..."

And that's when it happened.

The thick fog inside the crystal ball seemed to thin a little, and an image started to form. My eyes widened.
"She... she's not moving..." I said, my voice catching in my throat. "My — my mother's there... and — and my father... they're both laughing... and — and—"
I stopped mid-sentence as I saw the rest of the image.

"And...?" Trelawney prompted, scribbling keenly on the parchment perched upon her knees.
"I-I'm there," I said quietly, "I-I'm kneeling next to the girl... I-I think she's..." My voice trailed off. I swallowed, then whispered, "I think she's dead."
"Very good," she said, looking at me with a smile on her face.
I just continued to stare at the crystal ball; the image had already been consumed by the fog again.

"Can you see anything else?" Trelawney asked.
I just shook my head. I couldn't see anything other than thick white fog anymore, nor did I want to. Professor Trelawney sighed.
"Well, dear, I think we'll leave it there then... not too bad..."
Relieved, I got up, picked up my bag and turned to leave, but out of the corner of my eye, I was sure I saw a new image appear in the crystal ball.

It was me.

With the Dark Mark.
