Author's note about rating change: I've bumped up the rating to M. I wanted to keep it at T, but I read the guidelines and there will be strong language and some adult themes. Nothing explicit but maybe something blushworthy (at least I blushed), but I blush and have to look away from the screen whenever there is a kiss in Disney cartoons.

Part 2: The Deception

Teddy would have preferred it if her tone had been scathing and disgusted when he arrived on the Weasley's doorstep in Malfoy form. Then he could have gotten at worst a hex and been sent on his way to tell Ron that his daughter was still a firm anti-malfoy supporter. Then all of this unpleasantness would have been avoided and he would not end up feeling like a traitorous dirty old man. Unfortunately, her tone was not as scathing as one would expect from a Weasley finding a Malfoy on her doorstep.

Sure there was plenty of anger and surprise in her tone, but she also looked undeniably pleased to see him. Teddy didn't even get a chance to respond before she had grabbed him by the wrist. She glanced out the door looking around for any witnesses before closing it hurriedly. "Your just bloody lucky everyone is out of the house." Luck had nothing to do with it. Ron had arranged for Rose to be alone, so she would be completely candid in her reaction to Malfoy's appearance. Teddy was pretty sure Hermione would suspect something was going on when Ron took her on a surprise date, but who in their right mind would figure out exactly what Ron was up to. Hugo was at a quiddtich camp for the next two weeks, so he wouldn't be a problem. "Merlin, if my father saw you…I don't even want to think about the number of healing charms I'd be using to repair your mangled body." Rose continued to hold on to his wrist which was making Teddy uncomfortable. She was pulling him up the stairs in the direction of her bedroom causing warning bells to go off in his mind. He knew he should stop this now, he had enough information to get her grounded for the rest of the summer, but he didn't know the nature of Malfoy's and Rosie's relationship. They might just be good friends or something.

She shut her bedroom door behind them. Teddy hadn't been into Rosie's bedroom for years. It hadn't changed much. It looked like the room belonged to an eleven year old girl: pink walls, flowery bed sheets and drapes, the usual girly mess that occurs when children are allowed to decorate. Rose noticed him eyeing the room and blushed slightly. She punched him in the shoulder softly. "Stop judging! It didn't seem important to redecorate a room I only stay in three months of the year. I'm about to leave anyway and I know it would kill Dad if I changed it now," Rose tried to explain.

Teddy smiled crookedly, "I wasn't going to say anything." It was the first time Teddy spoke using Malfoy's voice and it made him start slightly. He had forgotten that he was supposed to be someone else for a minute. Rose cocked her head to the side and examined him. Her red curls spilling over her shoulder. Teddy dropped the smile quickly. Did Malfoy smile? He had never seen Malfoy smile. Oh Merlin, Rose was going to figure it out and hate him forever.

"I've missed you," she breathed out softly. There was a deep sad happiness in her blue eyes that made Teddy's gut wrench. He had a dirty taste in his mouth and was wondering what he was doing here. Would it be so bad if Rose was in love with a Malfoy, if she was happy did it really matter who it was with.

Teddy figured he should say something before he really mucked things up for Rose and Scorpius. "I missed you too. Not even death at the hands of your father could keep me away," he told her smiling slightly. Now, if he could just slip away before she realized what was going on all would be well with the world. He could make his excuses to Ron and worry about the confusion between Rose and Scorpius when they owled later. Maybe, he could intercept and change all of the owls Rosie Posey was sending Scorpius and neither of them would ever figure it out.

Rose smiled up at him before moving her hands to his chest. "My parents are going to be gone for the rest of the afternoon and my brother is at some camp. It's better than Hogwarts." Rose looked up at him from under long russet eyelashes.

Better than Hogwarts for what? She couldn't possibly mean… Teddy's throat seemed to have gone completely dry. He couldn't think of little Rosie Posey doing anything…like that or ever looking at anyone like that! "I…uh…I…" Teddy stuttered horribly.

Rose giggled at him. "I've never seen you so flustered before," she said coyly fiddling with the collar of his shirt.

"It's just your father…" Teddy tried.

Rose growled in frustration, "I'm sick of worrying about my father." Before Teddy knew what happened, Rose had wrapped her arms about his neck and pulled him in for a kiss. Teddy's arms had automatically wrapped around her waist, but his shoulders tensed and he didn't immediately return the kiss. He was…well Teddy didn't know exactly what he was feeling, but it wasn't what he expected.

Rose pulled back slightly in question looking confused and hurt, but before she could say anything Teddy leaned in and pressed his lips against Rose's. Teddy for the life of him couldn't figure out what he was doing. Given a couple weeks to think it over he still couldn't tell you what made him do it. All he knew was that his brain clearly wasn't functioning and wasn't about to start working any time soon.

Rosie sighed into his mouth. She ran one hand behind his shoulder blades and the other wrapped up in his platinum blonde hair. It felt…different. Normally his hair was several inches shorter, and her fingers running through the longer locks felt off. It almost brought him back to his senses, but her tongue had darted into his mouth distracting him as she wrapped one of her legs around his trousers. She tasted of salt and slightly sweet from orange juice. There wasn't the slightly waxy flavor of lipstick that he got when kissing Victoire.

Teddy groaned in frustration recalling his girlfriend. Unfortunately Rose mistook it for a groan of passion and pulled him down to the flower colored duvet. She began slipping the buttons of his shirt out of their appropriate holes while continuing to kiss him. She raised her leg slightly causing it to brush a very sensitive area which made him groan once more for very different reasons. Rosie smiled wickedly at him. Her face was flushed and her chest was heaving occasionally brushing his own.

Teddy Lupin was definitely going to hell or whatever afterlife existed where you were tortured for an eternity. He began kissing her earnestly his hand slipping under her green shirt. Her skin was soft and felt like it was on fire. She gasped into his mouth as his hand ran up her side. Teddy smiled against her mouth in pleasure before moving down her jaw and to the crook of her neck with small kisses. Her skin tasted wonderfully clean. It was of salt and a slightly soapy taste without the bitter residue of perfume. Rosie moaned in pleasure and wrapped her legs about his waist pulling her body closer to his. She ran her hands up and down his bare back sending tingling sensations down his spine.

"Merlin, Posey," he growled into her neck. The second after the words left his mouth Rosie's body went stiff as a board. Teddy pulled back slightly pressing his eyebrows together in question. Rose had the look on her face she gets when she's figuring something out.

"Scorpius?" Rose breathed out her voice trembling slightly. She put a hand on his chest pushing him off of her further. Teddy put his hand over hers pressing it more tightly to his chest. "Oh Merlin…Teddy," she said in a barely audible whisper.

When Teddy did nothing to respond except cast his eyes away slightly, Rose jerked her hand away from him as if she had been burned. She covered her mouth with her hand and looked at him in disbelief. "The smell…the smile…you even tasted different," she nearly shrieked. He could tell she was on the verge of hyperventilating. "I should have known…I should have known…I…I cheated on him." She pulled her knees up to her chest and wrapped her arms around them protectively rocking slightly. Teddy didn't know what to do. He thought he felt guilty before, but it was nothing compared to this. He just stayed where he was on the bed embarrassingly shirtless and still in the form of Malfoy.

He tried to reach out a hand to her in a comforting gesture, but she smacked the arm away. "Don't you dare touch me," her voice shook with fury. Tears were streaming down the side of her face. "You have no right." She closed her eyes in a desperate attempt to shut out the sight of him. "Don't…I can't…look at him anymore."

Teddy swallowed the dryness in his throat and let the façade of Scorpius Malfoy slip away until Teddy Lupin sans his turquoise hair was left sitting on her bed. He wasn't keen on using any of his metamorphagus abilities at the moment. "Posey…I didn't…" Teddy didn't know what to say after that.

Rose opened her eyes and looked up at the ceiling desperately. "Posey…that's…only you. No one else…only you," Rose muttered refusing to look at him.

Teddy grabbed on to her shoulder and shook her slightly, "Rose, snap out of it. You're not making any sense.

"You're the only one who calls me Posey," she nearly shouted twisting out of his grasp and standing up. She was looking out the window hugging herself with her arms. "I thought I was imagining it at first. I haven't seen him for a few weeks, so I could be imagining that he seemed different. He wasn't different though, he was like you." Fresh tears were starting in her eyes. "How could you…how could you do it Teddy." It almost sounded if Rose had choked on his name.

"Rosie, I…" He gestured desperately. He couldn't explain his actions and he was unsure if he should reveal the motivation that brought him here in the first place. He didn't really want to create a rift between Rose and her father on top of what he had already done.

"Was it for a bit of a laugh? Did you and James think it'd be funny to mess with dear old Rosie?"

"Rose, I would never…"

"Never what…trick me? Deceive me? A little late for that Lupin," Rose spat.

"It was your father, alright," Teddy nearly screamed at her.

"What do you mean?" She looked at him suspiciously but waited for him to continue.

"He asked me to figure out if there was something going on between you and Malfoy," he confessed.

Rose snorted. "Right, by shagging his little girl while wearing a disguise. I'm sure that's exactly what Dad asked you to do."

The muscles in Teddy's jaw twitched. "No, that bit wasn't part of his plan. I don't know what happened, Rose."

"Merlin Teddy, you have a girlfriend. Whose my cousin I might add." She bent over and picked up his shirt. She chucked it at him with enough force to prevent him from catching it. It smacked his face.

"I know," he moaned in frustration. He quickly slipped on his shirt and turned away while buttoning it. Rose rolled her eyes and shook her head at his sudden modesty. The shirt was slightly tighter now that he was back in his normal form, so he left a couple of the buttons up top loose.

Rose seemed to have regained her composure and was looking at him with an unnaturally cool detachedness. "I want you out Teddy. And we will never speak of this," she said motioning about the room,"again. Understood?" Teddy nodded dumbly in response. You will also tell my father," she said the last word with disdain. "That I slammed the door in your face when you showed up as Scorpius." Teddy nodded once again. "And I don't want to see you the rest of the summer. If you're invited to Weasley gatherings where I might be, you make an excuse not to be there. I never want to see or speak to you ever again Teddy Lupin." Tears were once again falling down Rosie's cheeks and dripping onto her pale pink carpet.

"Posey," Teddy said placing his hands onto her shoulders. "How can I earn your forgiveness if I can never speak to you," he whispered.

Rose looked up at him her eyes weighted with sadness and clouded by tears. "You can't."

"I'm sorry Rose," Teddy said desperately. "I don't want to lose you."

"You're already too late Lupin. Now, Go…" she turned away from him slipping out of his grip.

"Rosie," he tried again stepping towards her.

"I said, Go!" she shouted and in a burst of uncontrolled magic, Teddy was pushed out the door and it slammed shut in front of him. Teddy leaned against the hallway wall and slammed the back of his head against the wallpaper repeatedly. He waited for ten minutes before finally leaving the house. Teddy Lupin needed Rose to forgive him and he was willing to do anything to make that happen.
