"You're late." Casey commented as Derek walked through the door after an evening working at Smelly Nellies.

"And you're annoying. So?" Derek remarked, taking off his leather jacket and throwing it onto one of the coatrack hooks.

"You've been coming home late an awful lot lately." She continued.

"And?! Why do you care what I do with my evenings?!"

"I don't I just want to make sure it doesn't effect me."

"Well, it doesn't, so will you get off my back?" He said, going upstairs before Casey could hassle him any more.

~A Week Later~

Derek was still acting weird, well Casey thought so, anyway. He was always coming home late, sneaking out and having secretive phone calls. Casey was very suspicious and needed to know what he was up to. Knowing him, it was most likely something bad, and evening though Derek said it had nothing to do with her, she had to make sure. For all she knew, Derek could've been planning some huge prank to humiliate her at school with.

So, one night at around the time she knew Derek's shift would be ending, Casey went to Smelly Nellies. She snuck into the restaurant just before it closed and hid under one of the booth tables. She saw Derek come out from the kitchen and watched as he took his apron off and hung it up. He then fished his phone out of his pocket and smiled at it, before walking over to the door and opening it, letting a pretty girl with long Y/H/C hair step inside.

"Hey." Derek smiled and Casey gasped when Derek leaned down to kiss the girl on the lips. So that's what he'd been up to!

"Hey, you ready to go?" The girl asked, smiling back up at him.

"Yep." They started to leave, so Casey tried to get up to follow them, but hit her head on the table in the process. Derek and the girl were barely out the door when Casey yelped in pain and they both turned around, finally realising she was there.

"Casey?" Derek yelled as she crawled out from under the table.

"Oh, hey..." Casey awkwardly trailed off.

~~~

"I can't believe you did that!" Derek yelled as he followed Casey into the house, where they were greeted by the curious faces of their family who were all watching TV.

"I'm sorry, okay? But you left me no choice!" Casey argued.

"Why couldn't you have just minded your own business?!"

"Whoa, whoa, what's going on?!" George finally intervened.

"Casey came to spy on me when I was finishing at work and she ruined my date with Jordan!" Derek explained angrily.

"Who's Jordan?" Lizzie asked.

"Derek's girlfriend, who he's had for, like, three months and didn't be tell us about!" Casey exclaimed, pointing an accusing finger at Derek.

"I don't have to tell you guys everything, you know!" Derek said, throwing his arms up in annoyance.

"Is that true, Derek?" George asked his son.

"Yes, okay, I have a girlfriend!"

"Why didn't you tell us?" Edwin asked.

"Like I said, I don't have to tell you everything!" Derek then sighed, "And, I guess I really like her and I didn't want you all to make a fuss."

"We wouldn't have made a fuss, Derek." Nora assured him.

That's when Marti started shouting, "Derek and Jordan sitting in a tree, K-I-S-S-I-N-G!"

Everyone else then joined in just to wind Derek up and he tried to act annoyed, but he couldn't help but smile.
