Author's note : Hi!!! Thank you so much as always for reading/reviewing last chapter. I'm really liking where this story is going. :-)

Enjoy this one and don't forget to review!!!

I can't believe this is happening. No, it can't be, Meredith kept repeating in her head over and over. How could this day have gone so wrong? How could Derek go from a cute neighbour, to a potential serial killer and now, a FBI agent?

She stood near Owen, arms crossed and eyes fixated on Derek. It was as though she was seeing him for the first time.

"Yeah, why would someone want to hurt Meredith?", Owen inquired.

"Does that mean Mark is an FBI agent too?", Izzie added in disbelief.

"Like I said, we don't have time for explanations.", Derek pressed.

He had to call the local police and the Bureau and most importantly, get Meredith far away.

"Listen", he started, turning to Owen. "Take Izzie and Cristina back into the house and lock the door."

"Wait, you said we had to leave! What if crazy guy comes back?", argued Cristina, who had now emerged from behind Owen.

"He won't. Not for now, that 's why I want you to call the local police and I'll ask my partner to come over. He'll explain the whole situation.", he explained." Now, I have to leave with Meredith. She is his main target so I have to take her somewhere safe."

"What about t-the..box.", Izzie asked.

"Leave it where it is. The forensic team will come and take it to their lab.", Derek calmly answered.

God, why is this happening to me? Why would someone want to kill me?!

Meredith took a deep breath. She had to calm herself down and do as Derek said. He was the professional; he seemed to know what to do. She had to trust him even though everything about him was a lie.

"Guys, I'll be fine.", Meredith said to her friends. "We'll just do what Derek says and everything's going to be alright."

Owen nodded while Cristina gave her a "don't worry" look. As for Izzie, she still seemed to be suffering from the shock of the situation and tears were threatening to cover her face. She stepped forward and gave Meredith a tight embrace. Hugs were not usually Meredith's favorite thing but, in that moment, she welcomed her friend with open arms.

"Be careful", Izzie whispered in the green-eyed woman's ear before reluctantly letting go.

"I will.", Meredith whispered, her voice laced with sadness and fear. Owen, Cristina and Izzie went back into the house, leaving the box near the steps.

"Let's go.", Derek said, taking out his car keys.

"Where are we going?", Meredith asked as they walked away. The coldness in her tone did not go unnoticed by Derek. He knew she probably felt betrayed and it killed him to see the way she was looking at him. All he wanted to do was hold her in his arms and tell her everything was going to be okay. However, he knew the chances of her letting him do that ranger from slim to non-existent.

"Somewhere safe.", Derek replied.

He opened the car door for Meredith and closed it as soon as she got inside. He then hopped on the driver seat and took out his cell phone. He dialed Mark's number and waited for an answer while Meredith looked out the window. She felt uncomfortable being near him in a closed space. The smell of his cologne tickled her nostrils and his hand was dangerously close to her thigh.

"Sloan."

"Mark, it's me.", Derek said. "Miller went by Meredith's house. I had to blow our cover."

"He came? Is everyone okay? Is Izzie okay?", Mark asked, panicked.

"Yeah, he just left them something on the porch. I need you to go there now and wait for the forensic team. Also, could you explain to Yang and Stevens the situation?"

"Will do. Where are you?"

"I'm with Meredith. We're on our way to Mrs. Grey's house and then I'll wait for instructions from the Bureau."

Mrs. Grey?! , Meredith thought. He know my mom? How does he know my mom?

"Alright, I'll talk to you later", Mark said before hanging up.

Derek put his cellphone back into his jacket and glanced at Meredith. He'd give anything to brush his lips against hers, just for a minute. He wanted to reassure and to apologize because he could see she was angry. He had to use an enormous amount of willpower not to caress her thigh with his hand, who was so close to her body.

"How do you know my mom?", Meredith inquired as Derek snapped out of his trance and drove away.

"It's a long story.", he sighed, watching the road.

"Then start from the beginning, I have all the time in the world right now.", Meredith said with sarcasm.

At least she's making jokes, Derek inwardly shrugged.

"You remember when your mother had a big surgery about two weeks ago? With four other surgeons?", he started.

"Umm....yeah, I remember. The patient died on the table.", Meredith replied, not seeing what this had to do with someone wanting to kill her.

Derek took a left turn and got on the highway.

"Well, the patient's father, Greg Miller, went crazy. He basically blamed your mother and the other surgeons for his daughter death, even though no one was to blame. He also told all the surgeons they would soon experience the pain of losing their child before being escorted by security out of the hospital", he continued.

Meredith frowned. Her mom hadn't told her anything about that. Actually, no one had heard anything about that. Usually, Seattle Grace was the first place to hear about Mercy West's affairs.

"Everyone thought Miller would sue the hospital but that didn't happen. Instead, Maria Esteban, the daughter of the neurosurgeon was threatened, and two days later, attacked. She is still recovering at Mercy West. A week ago, the three other surgeons, including your mother received threats similar to yours."

"Really?"

"Yes. The FBI was called and I was asked to watch over you in case something were to happen.", Derek said while maneuvering the steering wheel. Meredith was dumbfounded.

How could all of this happen without me knowing about it?

"Why didn't anyone tell me?!", she exclaimed. She couldn't believe her life was in danger and no one had even bothered to tell her about it.

"Your mother wanted to protect you.", he sighed, hoping she would understand. All he wanted was for her to understand. "We didn't know for sure if Miller was going to go after so I was assigned to protect you. In case something like what happened to night would happen."

Meredith massaged her temple. Too much information in too little time. Ever since Derek had entered her life, it had not been the same. She closed her eyes and tried to will away the "there's a mad man wanting you dead" thoughts. Derek watched intermittently as she slowly drifted off to sleep, with tension lines on her forehead.

"Don't worry Meredith, I'll be here for you. I'll protect you.", he whispered. knowing perfectly she couldn't hear him.
