'Lilly what have I told you?' Derek's voice was stern. Lilly pouted up at him, her little arms folded across her chest. She let out a heavy sigh. Derek raised an eyebrow at her and crouched down. Face to face. Lilly was his angel, but like every other four year old in the world, she had her moments, like now.

'Don't remember.' She said, little eyes challenging him.

'Oh really?' Derek said. 'You don't remember basic manners huh?'

'Manners are silly.' She said stomping her foot.

'I've had enough of this boldness. I don't know what's gotten into you today Lilly.' Derek said standing up.

'Auntie Lydia stomps her foot at Uncle Scott and Uncle Danny all the time.' Lilly said. Warning bells went off in Derek's head. As much as he loved his wife's best friend, he did not want his little girl to turn out like her.

'You are not Auntie Lydia. You are Lilly. Are you going to apologise for throwing your crayons on the floor?' Derek asked.

'I couldn't find the pink one!' Lilly wailed loudly.

'Ok. Naughty step.' Derek said wrapping his hand around her tiny arm.

'Daddy no!' She begged but he closed off his ears as he marched her towards the stair case. 'Daddy please no, Daddy!'

Derek put his hands around her tiny waist and lifted her to the fourth step. 'Now tell me what age you are?'

'Four.' Lilly pouted.

'Does that mean you're a baby or a big girl?' Derek asked, cocking his head to the side.

'I'm a big girl!' Lilly defended frantically.

'Do big girls act like you're doing right now?' Derek asked. He kept his tone neutral. He hated disciplining Lilly.

'No.' She whispered.

'Ok. You're going to sit here for four minutes and you're going to think about what you did and how you acted. And then we'll talk.' Derek said. He straightened his back before she could protest and avoided her eyes, marching back to the kitchen and grabbing his cell phone.

Lilly's on the naughty step.

He sent a text to Allison. Her reply was almost immediate. He smiled when he opened it.

Are you ok?

I'll live.

Derek sighed, two minutes to go. Lilly had been quiet on the step. He hated this part of parenting. Hated putting her on that damn step.

I want to break the fourth step.

Derek, you can't protect her from everything.

Even the naughty step?

He got no reply. He looked at the time on his phone. Four minutes was up. He made his way to where Lilly was sitting; tear streaks on her soft little cheeks. Kneeling in front of her he made eye contact.

'Daddy I'm sorry for being bold.' She said immediately. 'I'll never do it again.'

'I hope not because I don't like putting you on the naughty step.' Derek said holding his arms open. 'Thank you for apologising to me.' He said as her tiny arms folded around his neck.

'I'm sorry.' She said again. He carried her back to the kitchen, setting her beside the table. She started to pick up her crayons without being told to. 'I found the pink one.' She said in a tiny voice. It was below her chair.

'Well then, get on with the princess dress.' Derek said turning back to the island with a grin.

'Ok. Daddy?' She said.

'Yes baby?'

'I love you.'

'Son of a fucking bitch!' Derek hollered from where he'd smacked his wrist carelessly into the counter. Stiles and Lilly looked up from their place on the couch that sat in the corner of the kitchen. Stiles had Lilly's unicorn on his head like a hat.

'Daddy. That's five for the swear jar.' Lilly said, putting tiny her hands on her hips.

'In a minute.' He said through clenched teeth.

'Now please.' She said skipping across the kitchen and lifting the jar from its shelf. She held it out in front of him.

'I said in a minute.' Derek snapped.

'Daddy that was cheeky. You're not supposed to snap at your baby.' Lilly said knowledgably. Derek let out a huff of a breath. 'And huffing's naughty.'

'Lilly, give me peace for five minutes will you?' Derek said.

'Naughty step.' Lilly said.

'What don't be silly.' Derek said glaring at the little girl.

'I'm not being silly. You're being bold. When I'm bold you put me on the naughty step so I learn my lesson.' Lilly explained. Stiles let a snort out of his nose. Derek sent him a quick glare.

'Lilly, naughty steps aren't for Daddy's.' Derek reasoned.

'Why not?' Lilly asked.

'Because I'm a grown-up.' Derek said.

'And can't grown-up's be naughty?' Lilly asked.

'Sure they can but…' Derek said, he realised he was losing this argument. He needed something good and he needed it now.

'But nothing Daddy. Naughty step. Now. And if you giggle again Uncle Stiles you'll be on it too.' Stiles stopped with a choke. Lilly pointed towards the hallway. Scowling Derek faced defeat and walked to the staircase, sitting on the fourth step. He couldn't believe his four year old daughter was putting him on the naughty step.

'Now what age are you Daddy?' Lilly asked. Derek chocked for a second before he muttered his age. 'I didn't hear that.'

Derek glared for a second. When did his little girl turn into a monster? 'Twenty nine.'

'Does that mean you're a big boy or a little boy?' She asked. He got the feeling she was enjoying this.

'A big boy.' Derek said.

'Then why are you acting like a little boy?' She asked. Derek spluttered but she went on 'you'll sit there for twenty nine minutes. And think about what you did. Uncle Stiles?'

'Yes ma'am?' He called from the kitchen. Derek had the feeling he was torn between laughing and running.

'You time twenty nine minutes from now please.' She said giving Derek a stern look and marching away. Derek let his face fall into his hands. He wondered what ever in the world motivated him into wanting kids of any shape. He kept an eye on the hall clock, but the minutes ticked by slowly. He'd only been on the step for four minutes when the door opened and Allison came in, followed by Chris and Melissa.

'What are you doing Derek?' Allison asked.

Derek opened his mouth to answer but Lilly beat him to it, running to meet her Mommy. Harvey was asleep on Chris's shoulder. 'Daddy's on the naughty step for being bold. Don't talk to him please.' Lilly said leading them away. Melissa sent him an amused smile while Chris looked away completely and Allison's shoulders shook in laughter.

'What did he do?' Allison asked Lilly.

'He'll tell you when he's finished.' She said darkly.

Peter and Del came through the door next. Derek had been sitting for sixteen minutes. Peter raised an eyebrow but Lilly was there before Derek could communicate. 'Daddy's on the naughty step. He's not allowed to talk to anyone. He's thinking about what he did.' She said. She waved hello to Del and Del waved back, taking her hand and following her into the kitchen.

When Jackson, Scott, Lydia and Danny arrived Derek only had two minutes of his time left. Lilly jumped into Jackson's arms, snuggling against him and kissing his chin. By now, Derek kept his head buried between his arms. 'What have you done?' Lydia asked, her voice dripping with mirth.

'Daddy was naughty so he's thinking about what he did.' Lilly said.

'Nice one.' Scott said. Derek decided, right there, that he would get revenge on his friends, because they were having too much fun at his behalf. A moment later Stiles appeared. He tried to kiss Jackson hello but he was too busy laughing at the sight of Derek.

'Lilly, twenty nine minutes is up sweetie.' He said trying to hold his laughter at bay.

'Ok.' Lilly appeared in front of Derek. 'Daddy have you thought about what you said?' She said. Derek slid from the fourth step to his knees in front of her.

'Yes. I'm truly sorry I was rude to you baby. It was childish of me. I promise I'll never be rude to you again.' He said. Lilly threw her arms around his neck, kissing his face.

'Oh Daddy! You're the best in the world.' She cried. 'Thank you for apo…app…saying sorry.' She said.

'Apologising.' He said.

'That word.' She agreed. Normally if she couldn't say something Derek would make her repeat it until she got it but he didn't want to push his luck today. Instead he scooped her into his arms and joined his family in the kitchen.

It was easy to think of revenge for most of his friends. Scott and Jackson he would make swim in the sea early morning. They needed to strengthen their muscles; they'd gotten lazy with their medals handing on their walls lately. And Lydia, he decided, could do with overtime at the leisure centre. He'd talk to his uncle about that. Danny's car was in the garage for service; he would call a friend he had there and ask him to postpone returning it for a few days. Stiles's punishment would be a bit more complicated, and needed more thought that the others. And Allison, well, Derek had plans for renaming the chair that sat in the corner of their bedroom the naughty chair…

'Da!' A tiny voice called. Harvey was in his high chair, using his fork and spoon as drum sticks on his table top. 'Da! Da! Da!'

Derek leaned over and ran his hand over Harvey's head. 'You too.' He said. Harvey grinned and tossed his spoon in the general direction of the table. It landed in Jackson's lap. Jackson immediately tried to balance it on his nose, for Harvey's amusement. Stiles was laughing at his boyfriend when Derek realised that the only way to get revenge on him was to somehow convince Lilly to put him on the naughty step too. He looked at his daughter to find her looking his way, a happy smile on her face.

Sure she was a little monster, but she was his monster.
