Author's note : Hi everyone!!! All the reviews you wrote gave me so much inspiration! Thank you sooo much. I think the title pretty much explains what happens in this chapter. Enjoy and don't forget to review!

"Wait, what?", Alex asked Derek, completely confused. Derek ran a frantic hand through his dark hair.

We have to do something. Fast. Really fast!

"Look, we have to go now! Your sister is in danger. The guy she was with looked like he was about to beat her right here, in the parking lot. I heard him threaten her. He said they were going home. You know where that is, right?"

"Yeah yeah, I do.", said now a very worried Alex.

"Okay then, let's go. My car is right there.", Derek replied, pointing to his car. He took out the keys in his pocket and handed them to Alex. "We have to hurry, come on!". Alex quickly followed Derek to the car. They got inside and flew out of the lot. Alex drove fast, really fast.

"So, tell me what hapened. And who are you?", Alex inquired as he turned the wheel to take a left.

"I'm Meredith's friend. We met recently. You heard what happened to her yesterday?"

"Yeah, I did. Her wrist is really messed up."

"She claimed that she tripped on the sidewalk but that's impossible. She had bruises old and new all over her ribs so I think it has been going on for a while. Today, I was walking to my car and I saw him holding her by the mouth and yelling at her. She told me it was fine but it clearly wasn't. I heard him say that he would 'show her who's the boss' when they got home."

"I'm the one who introduced them! Damn it! She's my baby sister. I should have protected her"

"You couldn't have known. It's not your fault. I really care about her too, you know and I really wish I could've done something.". Alex quickly glanced at Derek's sad expression.

"I can see you really care, man.", Alex stated with sincerity, hands fiercly holding the wheel which got a nod in response.

I hope it's not too late. He will pay for this.

--------------------------------------------------------------------

Meredith jumped at the sound of Finn slamming the front door. She sat on the edge of the bed, waiting for him. Waiting for it to be over. By now, tears had already made their way to her chin. When Finn came into the bedroom, he had a belt in his hand.

"I'm sure this will help to get my point across cause you to be slow lately.", he declared, standing in the doorway. He tightly wrapped half of the belt in his hand, leaving a couple of inches loose.

"Get up.", he ordered. She shakingly stood up as he stepped forward with rage in his look. She closed her eyes and bit her lip. He was about to unleash his fury on her small frame when Meredith heard a voice identical to her brother's and the sound of someone being punched with force.

--------------------------------------------------------------------

They arrived at the appartment building a couple of minutes later. Alex, followed by Derek climbed the stairs two by two until they reached the second floor. In front of the door 23, Alex turned the knob who was surprisingly unlocked. They were led by Finn's angry barking to the bedroom.

"You piece of shit, get the hell away from her now!", Alex yelled before landing a powerful fist on the veterinarian's face.

--------------------------------------------------------------------

She opened her eyes to see Finn landing on the ground, holding his nose.

"Damn it", he muttered, while crawling out like a cockroach of the room.

"Can't take someone your size, though guy?!", Alex yelled while following him to the hallway, eyes clouded by anger.

Derek took this moment to run to Meredith and tenderly grab her face in his hands.

"Are you okay? Did he hurt you?", he asked with concern.

"No, I'm fine, I'm okay.", she replied, looking up to meet his gaze. "Thank you. If you and Alex hadn't come-"

"It's okay, don't think about it. Everything's gonna be okay.", he replied, putting his arms around her and holding her tightly. In truth, he did not want to think about what would've happened, had they come 15 minutes later. He was thankful she was safe and sound.

Thank God she's alright.

"Do you have a bag? You need to take some stuff with you cause you're not coming back here.", he asked, pulling away so he could look at her still in her scrubs and lab coat.

"Yeah, yeah", she said, sniffling snot, threatening to come down her nose.

She went to her closet and took a big traveling bag. She started opening the drawers to take out clothes and underwear while Derek took care of her shoes. He zipped up the bag and put it on his shoulder.

"We'll take the rest later.", he proposed.

We? , she thought, smiling interiorly at the fact that he planned to be around.

He grabbed her hand and they went out of the room. They passed by Alex still punching a bleeding and almost passed out Finn.

"I think he got the message", Alex observed, getting up. The three of them walked outside the appatment without a look behind. As they went down the stairs, Meredith noticed her brother's fist.

"Alex, your hand is bleeding!", she exclaimed, taking it in her hand to examinate it like he had done earlier today.

"Meredith, stop worrying about me. Are you okay?" he asked as they reached Derek's car.

"I'm fine. Thank you for being here.", she replied, as she took a step to hug her big brother. Derek watched them with a beaming smile. He was glad Meredith had a support system because she was definitaly going to need it. They got inside the car and drove away.

-----------------------------------------------------------------------

"I called Izzie and she said she would get your purse and your keys from your locker and bring them here.", Alex said, standing in the front door of his house.

"Thanks", Meredith whispered, from the indoor side of the entrance.

"I'm sorry I have this parent/teacher crap tonight and I can't cancel but I think you're in good hands with Derek here."

"Don't worry, I'll take care of her", replied Derek who was standing next to Meredith. He turned his head towards her eyed her tenderly. It had become a habit of his. He honestly felt like never leaving her out of his sight, even though hhe totally realized it was impossible. Still, he wanted to be there as much as he could to take care of her and maybe love her. Meredith met his gaze and smiled. She was glad she wasn't alone in Alex and Izzie's house. Izzie was still on call as well as Cristina and George. In the car ride, Derek had quickly agreed to stay with her until her brother and his wife got home.

"Thank you.", he said to Derek, holding his hand out. The blue-eyed man gladly grabbed the offered hand and shook it solemnly. After Alex left, they moved into the living room and sat on the couch in an non-awkward silence. They were side by side, their feet free of shoe resting on the coffee table. Meredith wasn't crying anymore. Sadness had long left the building and left place to anger. She was angry at Finn for controling her life and making her feel like she was less than a human being. She was angry at him for making her lie to her family and manipulating her into thinking it was her fault.

"That fucking asshole!", she thought outloud which made Derek raise and eyebrow and look at her with an amused smirk. Realizing what she had done, Meredith giggled.

"Oh sorry. I don't usually swear but Finn just brings it out of me."

"Don't apologize", he chuckled.

"I really want to thank you for what you did today. Thank you for being here.", she softly said. She put her hand on top of his and squeezed it.

"From now on ,you can expect me to always being here. Always.", he answered. "By the way, I really appreciate what you did today."

What I did? What'd I do?

"What are you talking about?", she asked with questions marks in her eyes.

"Trying to protect me by threatening to beat up my ex. No one's ever done that for me.", he said, impressed which made her laugh out loud.

"Yeah, I did what I had to do. She deserved it.", she stated with serious expression that Derek found adorable. Suddenly, Meredith put her hand to her stomach as it made a loud roaring noise. She shyly looked at Derek who then looked at her and chuckled.

"I haven't had anything to eat since this morning.", she explained.

"Since this morning?! It's 2 o'clock! You must be starving. You want to go out?"

"We could order something instead.", she suggested. Derek took out his cell phone to order some pizza while Meredith tried to find a good dvd in his brother's collection. They spent the rest of the afternoon, eating and watching a comedy. The movie made them both laugh several times which made them realize they had the same sense of humor. Yes, Meredith was laughing and having a good time in spite of today's disturbing events because that's what being with Derek did it her. When Izzie and Alex arrived home, hours later, they found the pair sleeping on the couch, Derek's arm around her shoulder and Meredith's body tightly snuggled into his chest. Alex bend down next to his sister and tried to get her in his arms to put her somewhere more comfortable than the sofa but was unsuccessful. Meredith was holding on to Derek's shirt as though her life depended on it. She wouldn't let go, no matter how much Alex pulled her. Realizing all his efforts were in vain, he went up the stairs to his bedroom and came back down with a blanket to cover their sleeping forms.

Don't think for a second that Derek is done with Finn.....
