The Unicorn and the Stag

Chapter 18

Rose's classes were much more interesting with Ginny around. She had filled out quite a bit over the summer, so all the boys kept goggling at her. It was always fun to embarrass boys by calling on someone and they were too busy staring at someone's bust to know the answer. Ginny also seemed to take after the twins; she had a tendency to play pranks on the other students. Rose loved pranks, and even devised the Great Weasley/Potter Conspiracy.

She actually came up with the idea. She needed revenge on Professor Snape for taking those fifty points off Gryffindor when Harry needed to get to the clearing for the Rainbow Spell. Harry was doing some Charms homework and she was inspired by his turning Ron's dress robes dark blue.

"Harry!" she said suddenly, making him jump, "I have my revenge plan! Where are the Weasleys?" Harry pointed to the fireplace, where all five Weasleys at Hogwarts were talking about Bill and Rose's wedding.

"Fred! George! Do you want to play another prank on a Slytherin?"

The Weasleys sat up instantly.

"You two," she said, pointing at the twins, "how do you work that red and gold charm you put on Malfoy's hair?" Harry heard them and came over. He wanted to help.

"Here's my plan. I buy Snape new robes. He always makes me do it. I bring them up here. Some of us alter Fred and George's charm to make it only activate when Snape puts on the robes. We curse his potion ingredients so they'll do the opposite of what they're supposed to. I deliver him his robes. He usually puts them on the next day. He puts on the robes, they flash red and gold, and I'll charm them so he can't take them off for a week. He gets even more embarrassment when he makes a potion to demonstrate for his class and it blows up in his face. It should work out perfectly."

Potions the next day was wonderful. Snape came swooping into the dungeon, which was much less intimidating than usual as his robes were alternately flashing red and gold. Several Gryffindors snorted, but were immediately silenced by a Death Glare.

"The ingredients for the Draught of Peace are on the board," he snarled, waving his wand. "You have ninety minutes. Begin."

Ron, Hermione, and Harry kept glancing up and watching Snape as he threw ingredients into a potion bubbling on his desk. Then he frowned slightly as he noticed the color. It was pink. The Draught of Peace was supposed to be blue. He leaned forward to take a closer look...and it exploded all over his robes. Snape took fifty points from Gryffindor just out of pure spite, but it was worth it, as the stains and burn on his robes was there for the rest of the week.

*~*~*

"Rose, what's this surprise that you teachers keep talking about?" Harry asked.

"I can't tell you just because you're my brother! You'll learn eventually!" Rose said indignantly.

"Come on," Harry whined. "Please?"

"Fine. It's a field trip."

Over the next few weeks, everyone was passing around rumors about the field trip. Rose was the teacher assigned to the trip. Her job was to make sure that no one died and that the prefects organized it right.

"You are to place the students in groups of four, two girls, two boys, and one from each house. They will travel with their groups, not the whole student body. Only fourth, fifth, and sixth years will be going. It will be only to Muggle areas, so no magic is allowed unless absolutely necessary. There will be a trip to Muggle London January 2 to shop for the trip. You are allowed fifty necessary items. They can be shrunk. The trip will last three months, February, March and April. You must work with the other houses' prefects."

The prefects from the other houses were Susan Bones and Justin Finch- Fletchley for Hufflepuff, Terry Boot and Amanda Blocklehurst for Ravenclaw and Pansy Parkinson and a tall, black-haired boy named Dameon Morkin for Slytherin. Harry and Hermione were put in charge of choosing places to visit. The Hufflepuffs formed groups, the Ravenclaws made a list of supplies, and the Slytherins set up days for checkpoints, to make sure everyone was alive. The checkpoints would also have a quick written test on what they had learned about the Muggle world.

Harry and Hermione began accepting suggestions for where to go. They were to pick ten spots anywhere in the world. It had to be something interesting to all the years going. They began with the Bahamas, went on to Florida, then moved to two spots in California, then Salem, then New York City, then France, Russia, Spain, and Ireland. They were supposed to get to Ireland on June 21, when there would be a celebration if everyone got back alive. Rose was excited about it, herself. The professors had insisted someone go with them, and since Rose was the most liked teacher, she would go. She was to stay with the prefects and handle any problems. This pleased everyone but Bill.

*~*~*

Before anyone knew it, it was Christmas and time for the ball. Ginny and Hermione had agreed to shop with Ginny for her date with Harry. Luckily, there was a Hogsmeade trip a week before the dance. Unfortunately, they were having a bit of trouble.

"Mione I have no clue what to buy!" Ginny wailed. "What's Harry's favorite color? What color are his robes?"

"Ginny, calm down. If Harry likes you enough to ask you to the ball, he shouldn't mind what you wear much."

"I care what I wear! If I don't look gorgeous AND match Harry, the Slytherins will never let me live it down!"

Hermione slowed her frantic pawing through the robes. "Which Slytherins?"

"Pansy Parkinson, Blaise Zabini, Millicent Bulstrode. Their boyfriends, too. Zabini is Goyle's and Bulstrode is Crabbe's. Parkinson is Malfoy's, of course."

"Those two hulking idiots have girlfriends?"

"I don't know how they got them! Just help me find some robes!"

"Having trouble, Miss Weasley?" said a voice from behind them.

The girls whirled around. "Oh, it's just you Professor," Ginny said, seeing Rose.

"Rose, please, Miss Weasley, Rose."

"Not until you call me Ginny. Miss Weasley sounds weird."

"All right, Ginny. And Harry's favorite color is forest green, and his robes are Gryffindor red."

"Oh THANK YOU Rose!" Ginny jumped up and hugged her Professor and went back to frantically looking for a good robe and something to wear under it.

"Might I suggest these?" Rose said, holding up a gold shimmering dress with deep red velvet trim and robes of the same red. Ginny smiled. A professor being helpful in something other than school. Well, she was her future sister-in-law.

"Is that the same red as Harry's robes?"

"Exactly. Here, I'll pay."

"No."

"Please can I pay?"

"Prof - Rose! I'm not poor!"

"No, but I'm sort of your sister. So I'm paying. I picked, I'm paying. Look at the price tag and you'll appreciate it."

Ginny shut up and let her professor pay. It was slightly weird to have her sister-in-law also be her boyfriend's sister, professor, and friend. But she could deal.

"Rose, let's go to Honeydukes!" she said.

"Great! I love it there. And can we go by Zonko's afterward?"

"You like Zonko's?!"

"Sure, always remember the Great Weasley/Potter conspiracy and who though it up. Man, Snape looks good in red and gold." The girls snickered. "And that scorch mark - the sunburst design is quite nice."

"Yeah, he might start a whole new look for the Slytherins!" Ginny said.

They left Honeyduke's with a lot of the new flavored Sugar Quills, Chocolate Frogs, Bertie Bott's, and some levitating sherbet balls. They bought some Christmas presents for Fred and George and a few new things for Snape at Zonko's.

They met up with Harry and Ron in the Three Broomsticks to talk about the recent Gryffindor/Ravenclaw game, which ended in Ron imitating the Ravenclaw Beater's being whacked in the head with a Bludger and knocking over everyone's butterbeers, causing Ginny to whack him upside the head and dump her remaining butterbeer on him. Everyone returned to the castle soaked with butterbeer and laughing.

*~*~*

After the butterbeer fight in the Three Broomsticks, Rose desperately needed a bath. She went into her bathroom, which was the size of a high- school gym, peeled off her soaked clothes, and started drawing a bath in her swimming-pool sized tub. She filled it with her favorite bubbles and climbed in.

She sat there for a long time, drawing in the flower scent of the bubbles when an owl flew through the window in the door. It dropped a letter at the side of the tub and flew off. She picked up the letter curiously and opened it. It said:

Hello, Rose. Long time, no see.

Rose slowly turned to look at the door of her spacious bathroom and saw someone she had hoped never to see again.

"Hello, Rose," Voldemort said, his fiery red eyes glinting evilly. "I've missed you, but I've certainly seen your brother."

Rose ran her hand along the length of her body, and suddenly she was wearing a red and gold robe.

"I'm going to kill you this time," she said. Her blue eyes began to glint violet. "I'm not just a helpless little girl now. I can kill you. My brother will get you if I don't, if he doesn't, my husband will. If he doesn't, one of his brothers or his sister will. Getting the picture?" she hissed.

Voldemort laughed. That laugh pissed her off! "Little Rose, your friends' power is nothing to mine. My Death Eaters and I will always be many, many times as powerful as you." He laughed again. Now Rose was REALLY pissed. Her eyes turned dark purple and suddenly Voldemort couldn't go towards her. She was so furious sparks were flying out of her fingers.

"Remember who won in the end, huh? Who won, Godric Gryffindor and his friends or the lone Salazar Slytherin?! Who do you think will win this time, the heirs of the winners or the heir, singular, heir, to the loser?!"

Rose's fingers weren't just emitting sparks now; there was a stream of deep red light coming from the ends of her fingertips. She brought her hands up and clasped them together, then brought them outward with a blast that would have stopped a tornado.

Voldemort disappeared. The last thing she saw was him vanishing in a cloud of green smoke. She then passed out.
