As I scored the winning goal for the grand finals, a beautiful brunette comes skating across, the way she glided across the ice made me shiver. She was amazing, but as she neared I still could not properly make out her features. The girl stopped only a few inches from me and she had let her blades sprinkle a coating of ice all over my clothes. My breath caught when I looked into her startling blue eyes and realised who the girl was, Casey. Even after realising who she was I still leaned in and let my lips lightly touch hers.

Derek groaned in frustration as he realised that once again he had dreamt about Casey. He smacked his head on the bed board in an attempt to knock all thoughts of her from his mind. Today he had to focus because today was the day that would mean that he would never be able to date Casey, today was the wedding.

He glanced over at his alarm clock, it was only 7:00 am, but he wasn't going to risk dreaming about Casey again so he hopped out of bed and went to take a shower. Derek had thought that the shower would clear his mind and allow him to think about the important things. Things like pranking Casey today, but the shower had just led to thinking about how Casey would be using this shower soon, and he did not want those thoughts at all. So it was too early to get ready which meant that there was only one thing to do, TV. Cartoons would numb his mind, and soon enough Edwin would be up soon to make him breakfast. As he sauntered down the stairs Derek noticed that Edwin was already up. "Hey Ed, Captain Crunch now" Derek ordered as he sat down in his chair.

In less than a minute Derek was wolfing down his cereal when Edwin asked "Are you excited for the big day bro?" Derek shrugged as if to say that he couldn't care less about his into life being turned upside down. Edwin's cheerfulness was bugging him though so Derek decided to try and take his frustration out on his brother. He tried to make his voice sound as innocent as possible when he asked "Hey Ed, what if you wanted to date Lizzie one day, what would you do then?"

Derek only became more agitated as Edwin began to laugh and spluttered out "Me and Liz, you mean my sister? I have always known you were a funny guy, but that is hilarious Derek." Derek clenched his fist and mumbled "Step Sister Ed, not sister." Derek had blanched when Edwin had used the word sister, trying to imagine Casey as a sister was torture. Marti was a sister, Casey, was well everything except that. As this little chat had done nothing for Derek's mood he ordered Ed to go get him some more cereal. As Derek sat alone he decided that he would make Casey hate him, well not entirely because then he wouldn't be able to function properly but just enough to keep her the object of his pranks not affection. He slowly let his mind drift back to the cartoons when he realised that Ed wasn't back with his cereal.

Derek shouted "Ed you have ten seconds to bring me my cereal or your toast, and speaking of toast you after my cereal grab me some."

But even as he yelled at Edwin he couldn't help but think that when it came to Casey he was toast.

It was two hours before the wedding and the Venturi household was in disaster mode. Marti's flower girl dress was missing, Edwin had spilt soup on his tux and Derek was in the bathroom fixing his hair. As he stared at his reflection he realised that no matter how perfectly dishevelled his hair was it wouldn't make a difference to Casey. Derek himself was ready to go, he was dressed and he was prepared for his after ceremony prank. But as he walked downstairs he heard George say into the phone "Thank you and tell Casey how much I appreciate her coming over to help. Love you Nora".

Derek froze mid step which was not a smart plan as he was on stairs and he began to fall. After a quick recovery he righted himself and used the wall to keep himself steady. His thoughts were all jumbled, Casey coming over now, Casey here with me now, Casey helping, Casey might find my prank gear if she is riding with us, Derek quickly shoved the 3 bottles of champagne and set of permanent markers into his backpack along with a bandage. Everything had to go according to plan or else he would be stuck looking at Casey being all smug and perfect while he suffered inside.

Derek walked to the car, threw his backpack into the car and walked back to the house, as he was shutting the door he heard a car pull up the driveway. As he walked inside he shouted "There here." And sprinted up the stairs to escape from her, as he reached the top he saw Marti curled up in a corner.

"Now come on Smarti, what's the matter? I thought you wanted two new sisters and a mum" he asked in a tone he reserved for Marti alone.

"I do Smerek, it's just that I heard you saying to Sam last night that Casey, Lizzie and Nora would be gone soon enough. I don't want them to go Smerek." Marti sobbed.

"Smarti I was only joking, Nora, Lizzie and even Casey are going to be here as long as you want after today and now come on let's get you ready" he said.

"Yay, Wedding" Marti shrieked and ran off to see Nora, Lizzie and Casey.

He had only been putting up an act of bravado in front of Sam. Because if he was being honest with himself he didn't want them gone, especially Casey because as much as he could try to deny it, he would rather live with her as a brother than not at all. Now after helping Marti, Derek had reached the end of his rope with all this emotional stuff, now he was going to focus on the prank.

A/N Alright I know we haven't had a Dasey moment between Derek and Casey yet, but next chapter is the wedding and the prank!
