A/N: Hope you guys enjoy! I wanted to show Derek in an all new light.

If there was one thing that made Derek Morgan crazy, it was his four kids.

He loved them all dearly, and he had since the day they were born. He wore his overprotective badge with pride.

Avery, Chloe, and Kylie knew how overprotective their dad could be. When Avery brought home her first boyfriend, Derek had scared the boy shitless. When Chloe kept getting benched in her basketball games, Derek fought for her. When Kylie was being bullied at school, Derek marched into the principal's office, scaring everyone in his path.

Sebastian, his youngest and only son, also knew Derek wasn't to be messed with. When he colored on the wall when he was four, he was grounded for two whole weeks. It had seemed like an eternity to the young boy.

Sebastian was eight now though. He knew better than to use his crayons on the walls. That's why he was coloring and swinging his legs back and forth at the kitchen table. He was trying to stay out of trouble.

"Have you seen my laptop charger?" Derek asked, walking in. "I can't find it anywhere."

Sebastian barely looked up from his coloring book. "I think Avery had it last night," he said. "She borrowed your computer for a little while. She had to work on a paper."

"Why couldn't she use her own laptop?" he asked. Sebastian shrugged. Groaning, Derek asked: "Is it in her bedroom?"

"Should be," Sebastian replied, swinging his feet as he talked. "That's where she was last night when she had it."

"Alright," Derek said. "Thanks buddy."

Derek headed upstairs, silently cursing at the fact Avery was gone to volleyball practice. If she was home, she could've fetched the charger herself. He wasn't entirely comfortable going through his 17-year-old's things. He knew Avery would go insane if she found out that he was going through her belongings.

He opened her nightstand drawer, hoping the charger was in there. He found all the traditional things. Avery had a small bible tucked away, a pair of reading glasses, and a night light. Derek reached toward the back of the drawer, and his fingers grazed a small box.

Confused, he pulled it out and gasped. It was Trojan condoms.

"No," Derek said out loud. "No, no, no."

Okay. Avery was having sex. She was seventeen, and it was expected of course, but Derek was still bothered. Was she being safe? She was heading to college in a few months and didn't need to worry about a baby. My god, Avery was too young to be doing this! She had just learned to drive not too long ago. She wasn't even out of high school yet.

His baby actually had to worry about these things now. She was almost an adult.

Derek collapsed on the bed, staring blindly at the box. His fingers were trembling. The brownie points Avery's boyfriend Alex had earned with him were slowly disappearing. He had come to respect the young man over time, but he was having a hard time with it now. Were they actually doing... it?

Penelope walked passed the room carrying laundry then. She saw Derek in his catatonic state and stopped abruptly.

"What's wrong?" she asked. Then, panicked: "Did something happen?"

"No," he choked out. "but I found these."

He held up the Trojan's, watching Penelope's reaction as he did so. She didn't seem surprised or shocked at all. "Okay?"

"They were in Avery's drawer," Derek explained, nodding at the nightstand. "I was looking for my laptop charger, and… they were tucked away."

"She's seventeen, D," Penelope said. "A lot of teens experiment with sex at her age."

"So?" Derek cried. "She's seventeen! She has so much going for her in the next few months. Graduation, college, and her first job. Avery knows better than this. This could ruin her future."

"Derek," Penelope breathed, coming into the room. "She's obviously taking precautions."

He couldn't look at her. He stalked over to Avery's bedroom window and stared down. It was only a few seconds before Penelope had her hand on his shoulder.

"You can't protect her for forever," she pointed. "She has to experience the world. Besides, weren't you having sex at seventeen?"

"That's beside the point."

Penelope bit back a laugh. Well, Avery has a good head on her shoulders. She's being safe. She's taking all the precautions necessary. She's on birth control too."

Derek whirled around. "What?" he sputtered. "When did she start birth control?"

"A few months ago," she said, surprised by his outburst. "She's been with Alex for two years now, so I figured it was time. I scheduled the appointment and went with her."

"My god, Penelope," he said. "Did you buy the condoms too?"

It was at her sheepish glance that Derek lost his cool completely. As soon as his wife averted her eyes, he threw the box of trojans across the room. They knocked a notebook off Avery's desk.

"Great!" he yelled. "This is just great! You've basically gave our daughter the go-ahead to have sex whenever she feels like it. You may have lost your virginity at fifteen to a guy at band camp, but that doesn't mean our daughter has to."

She scoffed. "What's that supposed to mean?"

"You were fifteen!" he yelled. "That's only a year older than Chloe! I can barely stomach Avery doing these things. Much less Chloe!"

He stopped to take a breath. He was shaking from where he was so angry.

"Why didn't you ask me if I was okay with this?" he continued to yell. "You didn't even tell me you took Avery to talk with someone. Or that she started birth control."

"It's a female thing," Penelope said heatedly. "I didn't think I should embarrass Avery by telling you. Besides, it wasn't a secret per say. If you asked, I would've told you."

"I can't even look at you right now," he said, throwing his hands in the air. "You must really want some grandkids, don't you? Do you want to just head out for the weekend and give Avery and Alex the go-ahead? Give them the house keys and everything?"

Without thinking, Penelope slapped Derek as hard as she could across the face.
