Disclaimer: Harry Potter is from the creative genius that is J.K. Rowling. I am not her. This is merely a fan fiction to tide us over until Book 6.

A/N: Someone e-mailed me and reminded me I promised to write a D/G fanfic in Catalyst. However, I personally feel Draco needs to be taught a lesson. So be prepared. ============================================================================

Under his invisibility cloak, Draco Malfoy made his way to the prefect's bathroom. He had heard rumors that Weasel and his mudblood had been meeting there late at night for some "extracurricular" activities. He hoped to catch them in a compromising position so he could tell Snape and hopefully get two of the amazing trio expelled.

Jiggling the handle to the bath, he noted it was locked. Even Weasel wouldn't be stupid enough to not lock it, he thought to himself before whispering "Alohamora"

Ginny Weasley was brushing her hair infront of the vanity when she heard what sounded like the door opening. She turned to a mermaid picture that hung on the wall beside her.

"Did you hear something Merrium?" she asked anxiously.

"No," the mermaid's singsong voice rang out. Merrium was a tad bit eccentric, but Ginny enjoyed talking to her after her baths. During them however, she made sure all of the paintings had a blindfold charm on them. Merrium would tell Ginny all sorts of rumors from all the houses. It was truly amazing about how much the portrait of Hogwarts gossiped.

Draco heard voices. An evil grin formed on his face at the thought of finally getting rid of two of the dream team. However, when he turned the corner he only saw one person and it wasn't Weasel or Granger. It was the littlest Weasley in nothing but a large nightshirt.

A feral smirk graced his face. Maybe this wasn't a total waste after all.

Ginny felt as if someone was watching her. She looked at the reflection of the bathroom behind her in the vanity mirror as she continued to brush her hair. There. For a brief second she swore she saw someone's shoes by the tub's faucets.

"Hello?" Ginny said nervously as she motioned for Merrium to be still. "Is someone there?"

Draco smiled as he watched Ginny get up and take a few cautious steps forward. The nightshirt was clearly from one of her brothers. It was faded and laid rather high on her thigh. Draco noted that the littlest Weasley was hiding a lovely pair of legs under her robes.

Ginny thought frantically about the situation. She knew someone else was in the room with her, but she couldn't see anyone. It couldn't be a disillusionment charm. If it was she wouldn't have been able to see the shoes for that brief moment. An invisibility cloak? Those were very rare, could someone have one besides Harry? Wait a minute.

"Harry?" she said half guessing.

Draco felt his anger begin to boil over as the smile left his face. Why did she have to mention his name?

"Of course you would think it was your precious Potter," Draco spat.

Ginny turned toward the voice in shock. Malfoy? She quickly became very self-conscious about what she was wearing. Quickly she rushed to grab her bathrobe and closed it tightly around her.

Draco was steaming. Tearing off his cloaked, he crossed the room and angrily grabbed ahold of Ginny's upper arms and turned her so she was facing him.

"You have no problem flaunting yourself around when you think it's Potter, but cover yourself up like a nun around me," he spat nearly shaking her. "I bet you give Potty a private show every night. Not that he'd notice."

"How are you!" shrieked an outraged Ginny. Unable to smack him she brought her left knee up sharply.

Her aim was a little of, but it caused enough pain for him to release her. Quickly Ginny turned to run, but was unable to go very far as Draco had grabbed the end of the belt from her robe.

"You'll pay for that," he warned grabbing ahold of her arms again.

"Let go of me Malfoy or you'll regret it," she snarled.

"I don't think you're in any position to make idle threats," he hissed menacingly.

Just then, Ginny saw Merrium scowl in the portrait behind her. An evil idea started to take shape in her mind. A moment later a sinister smirk crossed Ginny's face unlike anything Draco had seen before.

"Idle threats," she nearly laughed, striking Draco dumbfounded. "Merrium, have you been listening to his?"

"Yes, I have and I am appalled," snapped a voice.

Shocked, Draco looked around for another person. All he saw was a mermaid portrait by the vanity scowling at him.

"Do you see him manhandling me? And Merlin knows how long he was watching under that cloak of his. He might make it a habit to watch people bathe," Ginny said hiding a grin as Draco released his grip on her.

"Scandalous," Merrium replied. "I should go tell the headmaster immediately."

The color drained from Draco's face. He would definitely be expelled if the mermaid told Dumbledore. Merlin even knows what all she would tell him. He looked at Ginny who was smiling wickedly. She had him at her mercy.

"Hold on a moment Merrium," Ginny said turning to Draco and whispered harshly. "You'll behave from now on Malfoy, and I don't ever want to see you in here or hear about you being in here again. I don't care if you're a prefect of not. If you even think about getting me for this, I'll tell Merrium to let Dumbledore know what happened here tonight. Do you understand?"

Shocked that a Gryffindor would do such a think, Draco just nodded.

"Good," Ginny said before turning to the portrait. "Merrium, I think he won't do it again. But if this happens again or he bothers me again I will let you know and then you can tell Dumbledore, all right?"

The portrait huffed for a moment, but agreed. Smiling Ginny picked up her wand and brush from the vanity. Draco stayed rooted to the spot where Ginny had blackmailed him. How did this happen?

Ginny passed Draco and opened the door to leave the bath. Before she did, however, she turned to look at him.

"Oh," she said sweetly, "by the way -"

She shot off her a bat-bogey hex before closing the door behind her.
