Isaac Lahey imagines

Defensive Jealousy

Dedicated to @BeautifulMax2001 for the idea!!

Everything was going well until a werewolf did something inappropriate.

Well, let's start with a little description, shall we?

Scott was quite the lucky guy, since he had you as a sister. No matter how many fights and arguments that you two got yourselves into, there was always the brotherly love that you could always count on.

However, Scott was very protective of you. Since you were a year younger than he was, he always made sure to warn you of the people to stay away from in Beacon Hills. That is...until you found Isaac.

The two of you had developed a romance that you had tried to hide from your brother, but it soon came out into the open. The pack accepted it with welcome arms, and you became one of the few humans that was allowed to know the supernatural business.

You leaned into Isaac's arm as you sat on Derek's couch and listened to him rant about some new threat that had popped up. Stiles yawned and stretched, but he accidentally hit Malia in the face when he did.

Malia lashed out and grabbed Stiles's arm, twisting it behind his back so that he yelped. Derek sighed and gave her an annoyed look,

"Malia, let go of Stiles. You might break him."

She raised her eyebrows, "Oh, someone sounds protective. What gives?"

"I don't want to get into more trouble with the Sheriff. If we bring his son in with a broken arm, I don't think he'd be too pleased. Plus, Stiles isn't trained at all. He's no match for you."

Malia pushed Stiles away and crossed her arms as she contemplated, "You're right. He isn't a match for me, or for any of us. If we don't kill him, something else will."

Stiles scoffed, "I can take care of myself! I have the bat, remember?"

Malia rolled her eyes, "I could break your bat, dummy."

Isaac surprised you by leaning close and whispering, "That's not all she could break."

You giggled, but you tried to hide it as Malia's eyes shot daggers at your boyfriend,

"Werewolf hearing, Isaac. It's a thing. You know, (Y/N) might be as helpless as Stiles is."

Your smile quickly died as you looked around at the thoughtful faces that turned your way,

"Oh no. I can already tell that I don't like where this is going."

Allison piped up from where she sat in the corner with Scott and Lydia,

"How about this. The regular humans can train with Derek or Scott for a while every meeting. Then, we can all be at least a bit more trained when dealing with the threats."

Derek stood up and looked around, "Alright, we only have Stiles and (Y/N) to train right now. Scott, you take one and I'll take the other."

Scott stood as well, "I call Stiles."

If Stiles was disappointed as he looked between Derek and Scott, he hid it very well.

Derek led you over to a bar that had been placed between two columns in the loft,

"I want you to show me how many pull ups you can do."

You shook your head, not bothering to tell him that you couldn't remember the last time you had worked out. You leaped up and grabbed the bar, and you only got in about 15 before you dropped to the floor. You shook out your aching hands and looked up to see Derek's reaction.

He raised his eyebrows, "This is going to be a lot harder than I thought. You have to be ready for an attack at ANY time."

You didn't register the meaning behind the words until Derek lunged at you. A yelp escaped your lips as he tackled you to the ground. He landed on top of you and placed his knees outside of your hips. With only one of his hands, he pinned both of your wrists above your head. You were completely immobile.

When you noticed exactly what this looked like to anyone else, your eyes widened and your cheeks flushed. Derek tilted his head in confusion to your reaction, but you quickly realized that you weren't the only one in the room who had taken his position the wrong way.

"Hey! I think that's quite enough training for today!"

You craned your neck to see Isaac storming over. He pulled Derek off of you by the back of his shirt and glared at him. Derek crossed his arms,

"We haven't even DONE any training, Lahey! What's your problem? You can't stand the sight of your girlfriend being tackled by another guy?"

Isaac's face began to turn red, "Yes! That's exactly why! If I have to watch my girlfriend being tackled to the ground every meeting, then I won't come to them! And, trust me, I can make sure that she won't either. I think I'll be training her on my own time from now on, thank you very much."

Derek just shrugged and walked to the kitchen while Isaac helped you off of the ground. When you both sat back down on the couch, everyone was trying to hide their smiles. Finally, Stiles broke the ice,

"Just be glad that Isaac was there to save you, (Y/N). Scott tackled me too, and it sure is awkward to be straddled by your best friend."

Isaac rolled his eyes as he pulled you closer to his side, "I'm sure that you were dying to be in her place, Stilinski."

Stiles glanced over to a certain strawberry blonde, "Maybe, but I have my sights set elsewhere, right now."

Derek returned to the living room and the boring conversation continued. It was no surprise that you quickly lost interest. You whispered to Isaac,

"So, you're really going to try to train me?"

"Yeah, why?"

You smirked and cuddled closer to him, "Oh, nothing. I just prefer you over Derek. Also,I think the order of events will proceed MUCH better."
