Title: Mr. Sensitive

Summary: Derek returns from a weeklong women appreciation retreat –Casey's idea- a changed man. At first everyone loves the new Derek, but eventually even Casey gets tired of Mr. Sensitive. Can she snap her stepbrother back into his old ways, or is 'Dereka' here to stay? Dasey.

Author: Silverflare07
Dedication: To Warlordess because she has to put up with me going on about Dasey and force shields and sock puppets that say Hola Georgie and she does it oh so gracefully. And because it's her birthday and since I can't buy her PKMN I'm writing about LWD.

Author's Notes: I originally got the idea from watching an episode of Family Guy, and if you've ever seen it you'll recognize the idea a bit. I promise that aside from the retreat and the new Derek nothing else is going to be taken from that episode. There will be no Derek trying to breast feed anything or worrying about being 'late'.

Extra Stuff: Fair warning to everyone...after the first chapter Derek is going to be extremely OoC. This is totally intentional and has to be in order for the story to make sense. His OoCness is going to affect everyone a little but especially Casey; she'll get pretty OoC too. Not as badly as Derek though, I can promise that. So if you don't like OoCness in characters I suggest you turn back now, because you will not like this fic. If you don't mind then enjoy. I hope this fic makes you laugh when you read as much as it made me laugh while I was writing it.

Stuff You Need To Know:

"Speech"

Thoughts

"Smerek's coming home today! Smerek's coming home today!" Marti cried in joy as she ran through the house. "Smerek's coming home!"

Nora laughed and picked up the energetic 8-year-old. "Are you happy to be seeing your big brother again?"

"YEAH!" Marti threw her hands up in a cheer.

From the couch Casey smiled. "Even I'm excited to see if this past week had any effect on him."

Edwin dropped down onto the couch next to her. "It's been a nice quiet week though."

"Shut up," Lizzie told him laughingly. "You know you missed him."

Edwin shrugged. "Maybe a little."

They heard the sound of the car pulling into the driveway and Marti wiggled out of Nora's arms. "SMEREK!" She yelled as she ran and threw open the door.

"Smarti!" Derek picked up his little sister and swung her around. "I missed you, Smarti."

"I missed you too, Smerek." She giggled. "Did you have fun at camp?"

"Are you kidding?" He placed her on the floor. "I had the best time ever!" He turned to everyone else. "And how's my loving family?" He pulled Nora, the nearest to him, into a hug.

"We're...great." Nora told him, pulling out of the hug and looking slightly confused.

"And how are Edwin and Lizzie? My two favorite tweens!"

The 'tweens' shared a slightly disturbed look before turning back to face Derek. "We're fine..."

They continued to stare at one another for another moment before Derek opened his arms. "Well...? Where's my hug?"

Slowly, both Edwin and Lizzie raised themselves off the couch and walked over to him. Lizzie gave him a quick hug before backing away and allowing Edwin to take his turn. Awkwardly, he leaned over and gave his brother a loose hug. Derek scooped him up, holding him tightly.

"I missed you, little bro." Derek told him.

"I, uh, missed you, too..." Edwin squirmed uncomfortably in Derek's grip. He had never been this affectionate with his brother before and, honestly, it was creeping him out a bit.

Derek let him go quickly before turning to where Casey was sitting on the couch. "And how's my favorite stepsister, hm?"

Casey's smiled lightly. "I'm good. Thanks."

Derek took three giant steps over to the couch and scooped her into a hug tighter than the one he'd previously had Edwin in. The house turned deadly silent.

"...What are you doing...?" Casey asked her voice muffled slightly by the fabric of his shirt.

"I'm giving you a hug. But I'm definitely not feeling the love back. Didn't you miss me even a little?"

Casey tried as hard as possible to keep the shock out of her voice. "S-sure." She placed her arms around him in what had to be the most awkward hug of her life.

"Well," Derek let her go and grinned. "I'm going to go unpack. I have so much laundry I need to do, you wouldn't believe it!" He picked up his bag and climbed the stairs.

"Um...who was that?" Edwin asked, watching where his brother had just disappeared from sight. "I thought Derek was supposed to come home today."

"I think..." Casey started, a smile spreading across her face, "that was Derek!"

Casey woke up the next morning later than usual. It was her last day of spring break and, just like the last day of summer, this was the day that Casey made sure was just for herself. She was looking forward to treating herself to a nice manicure and shopping trip. She also really wanted to try the new smoothie place that had just opened in the mall.

Sighing happily at the prospect of a peaceful day, she made her way into the kitchen and was surprised to be greeted with the scent of bacon, pancakes, and syrup. She was even more surprised to be greeted by the sight of Derek at the stove cooking the pancakes.

"Morning!" He turned to greet her with a smile and she almost choked on her own spit at the sight of him in one of Nora's floral patterned aprons.

"M-morning." She told him, taking a seat at the island. "What are you doing?"

"Making my wonderful family some breakfast." He replied before setting a plate of pancakes in front of her. "And here's yours; plain, with butter, and..." He reached behind him and placed two red strawberries on top of the small stack. "Some fresh strawberries to top it off. Just how you like it."

Casey looked around at her family who were watching the exchange in silent shock. "Um...thanks, Derek. That's really nice of you."

He leaned in smiling and bumped her shoulder with his playfully. "Anything for my Casey."

Edwin choked on the water he had been drinking and George almost dropped his silverware. Casey's eyes had turned the same size as her pancakes and she was seriously beginning to consider Edwin's alien replica theory. Derek turned away, oblivious of his family's reaction, as Marti walked into the kitchen.

"And would my Smarti like some chocolate chip pancakes?" He asked.

"YEAH!" Marti cried as she climbed onto the stool next to Casey.

Casey breathed a sigh of relief as Derek put the possessive 'my' before Marti's name. Of course it was just a sibling thing. The shock at his new attitude must have been what made her wonder otherwise.

Nora walked into the kitchen, stopping short when she saw her eldest stepson. "Derek is making breakfast?"

George nodded. "Yup, custom made to order pancakes."

If Nora was shocked at this revelation she got over it very quickly. "Well than, I'll take two," She glanced at Casey's plate. "Like Casey's."

Derek nodded. "No problem!"

Casey watched as her family enjoyed a nice breakfast. Today was going to be a good day. She could just feel it.

"So..." Derek's voice broke her out of her thoughts. "What are you doing today, Casey?"

Casey looked up from her pancakes. "I was going to head to the mall. It's the last day of spring break so I'm going to enjoy it."

"Great!" Derek practically beamed at her. "Can I come with you?"

Casey looked confused. "You want to come with me? As in - actually, voluntarily - spend the day with me? This isn't a trick to get to the mall so you can make up time for all the babe-scoping you didn't get to do this week, is it?"

Derek looked slightly horrified. "Of course not! First of all, babe scoping is insulting to women and it makes those women think less of the men. Besides, I thought we could use the quality time together. We hardly spend any time together as it is. I want to know what's going on in your life. I want us to be able to share things."

This time it was Lizzie who very nearly choked on her drink. Edwin tried his best to hide his grin as he thumped her gently on the back. Nora lifted an eyebrow at her husband who shrugged and returned to his breakfast. If there was one thing you learned from life with Derek it was that sometimes it was better not to ask. Casey was looking at her stepbrother in shock. Those words couldn't have passed from the lips of the Derek Venturi. She turned back to Derek and saw the sincere look on his face.

"Sure." Casey told him, smiling. "We'll have fun."

Derek smiled again. "Great! When were you planning on leaving?"

Casey shrugged. "About an hour, I guess. I want to go get ready and then we can head out."

"Okay." He nodded. "That'll give me time to clean up from breakfast."

The same shocked look passed over everyone's face. Derek...offering to clean... "Derek," Derek turned to face Nora. "That's not necessary. You made breakfast, I'm sure we can handle cleaning up."

"Well..." Derek looked unsure. "Are you sure? You guys already do so much around here and it wouldn't take me long to clean up."

Nora shook her head. "We'll take care of it. You go ahead and get ready."

"Thanks, Nora!" He leaned over and gave her a hug before slipping out of the apron and heading to his room.

George and Nora exchanged impressed looks and Edwin and Lizzie, horrified glances. What had happened to Derek?

Marti looked up from her plate. "I want more pancakes!"

There's chapter 2! I hope you guys liked it. I'm so much fun writing this Derek, he's so funny! And he's only going to get worse from here on out. And next chapter is the Dasey shopping trip! That should be fun!

R&R! Let me know what you think.

Come on, send me a smile!
