Vacation with Dasey
It was the day after the talent show for the marsh and the McDonald-Venturi family was getting ready to leave for home in the morning.
Casey, Derek, Lizzie, Edwin, and Marti were all on the dock watching the sun set. They started out quiet—they weren't fighting in some way for once—until Derek and Casey started nudging each other with their shoulders. The nudges quickly became shoves, and soon the duo was trying to push each other off the dock and into the lake.
Derek pushed Casey off first and stood their laughing as his stepsister angrily thrashed in the water—mad that her perfectly curled hair had gotten wet, making her hair straighten out. When she stopped yelling at Derek she decided she might as well pull him in too and grabbed his ankles, dragging him in.
When Casey wouldn't stop laughing at the surprised expression on Derek's face he splashed her, making sure to aim at her head. She immediately splashed back and the expressions on their faces quickly changed from laughing and carefree to serious and determined.
Meanwhile Edwin, Lizzie, and Marti quietly sat on the dock, watching their older siblings bicker, and making bets on who they thought would win.
"—Are you kidding? Derek got her hair wet, she is so not going to let him win now," argued Lizzie.
"Derek is the alpha dog, he would never let a girl win," countered Edwin.
"Can't we just go make s'mores?" interrupted Marti.
Lizzie ignored Marti's question, "Sexist much, Edwin? So what if Casey's a girl, she can still take Derek, just like how I can still beat you in arm wrestling—"
The conversation was interrupted as Casey dragged herself back onto the dock, stood, and ran toward the lodge with Derek hot on her heels.
