AN: As per usual I want to thank you for the reviews, the likes and the followings, I wish I could answer to all of you, but you need to log on in order for me to answer. Here is chapter four, hope you'll like it.

Lights will guide you home

Hearing his voice calling her name caused goose bumps to form all over her entire body "hi" she whispered, bending down to kiss him softly on the cheek.

"Hi" his voice was rasp.

"I missed you so much" she confessed, tears streaming softly down her face, exhaustion clear on her features.

"Wh… what happened?" he asked slowly.

"Let me inform the nurses you're awake, first" she gave him a quick smile and pressed the button used to call up the nurses' station. Less than two minutes later the nurse on call for the night entered the room "is everything okay Dr. Grey?" she asked.

"Yes Marla, everything is fine… Dr. Shepherd is awake" she explained, unable to stop the grin forming on her face.

"This is great news, I'll inform Dr. Hunt" she smiled back and left the room.

Meredith turned her concentration back on Derek "are you thirsty?" she asked, he merely nodded and she handed him a bowl full of ice chips "do you prefer water or ice chips?"

"Ice chip" he mumbled as she offered him a piece of the hardened liquid.

"Feeling better?" she asked after he had sipped on it for a little while.

He nodded and stared intently at her "what happened?" he asked clearer than before "I don't remember" he went on.

"You were in an accident" she said softly, taking his left hand in hers "you've been unconscious for almost a week. You had a subdural hematoma, your left tibia and fibula are broken and you had hematoma in your second, third, fourth and fifth ribs, you needed time to heal" he nodded, feeling pain all over his body "they took you off ventilation on the fourth day after the accident and you've been breathing on your own ever since" she added proudly.

"Zola?" he asked.

"She's good, sleeping I hope... she will be by with Bailey in the morning"

"Okay" he nodded giving her a weak smile.

That's how Owen and Alex found them, eyes locked, huge smiles on both of their faces "hey, it was about time!" Owen was grinning, just like Alex who got immediately by Meredith's side "glad to see you awake, man"

"Thanks Alex" he murmured.

"So, how do you feel?" Owen stood on the other side of the bed, looking at Derek.

"Like I was in a crash" he tried to be funny and the other three cracked a laugh.

They were still laughing and talking when Amelia joined them, about fifteen minutes later; Derek looked up seeming a little taken aback "Amy?"

"Why do you look so surprised, bro? You didn't think I'd come check up on my own brother?" she grinned.

"No, it's nice of course..." he still looked puzzled.

"How do you feel?" she asked getting close to the bed.

"Not too bad, but my chest hurts like hell and my head feels really confused..."

"It's completely normal after what you've been through" she reassured him "I'll take you for a CT and an MRI to see how that big head of your is doing"

"Sounds good..." it was Meredith who answered, holding onto his hand "can I come along?"

"Of course you can"

"Do you work here, sis?" Derek's question was accompanied by a vague grin and it took everybody by surprise.

"What is the last thing you remember, Derek?" Amelia sounded genuinely concerned.

"I remember being rescued from the plane crash..." he looked up at four worried faces "we were brought to a hospital in Idaho, Lexie didn't make it" he added painfully.

"Okay" Amelia nodded, trying to look calm "what year is it?" she asked.

"It's 2012, May to be exact"

The other four just looked at him, not speaking "what's wrong?" he asked when the silence went on for too long.

"I'm sorry Derek, but it's April 2015... it seems like you're suffering from retrograde amnesia" was his sister's answer.

He turned to look at Meredith, fear clear in his blue eyes "you know it's temporary" she tried to reassure him, squeezing his left hand.

"Yeah, I know..." he quietly answered back "but right now I'm missing three years of my life... of our lives?" he couldn't keep the hurt out of his voice.

"Your trauma was severe, Derek... it's very likely that you will regain your memories soon enough" his sister tried to calm him.

"Likely, not sure..." was his grim response.

"Well, you just woke up, give it time" Alex tried to reason with him.

"Sure... there is not much else I can do" he retorted.

"It will be okay" Meredith bent down to give him a kiss on the lips, melting into his touch when he responded to the kiss.

"Are you up for that CT scan and the MRI?" asked Amelia when they broke the kiss.

"Yes I am..." he gave his sister a smile "so, do you work here now?" he asked again.

"You bet I do... I've been working here for ten months and crashing at your house"

"Seriously?"

"Apparently we're still a magnet for strays" was his wife's answer.

"I had no doubt" he answered lightly as the three of them left the room, going to radiology.

After the exams were done and looked at by both Derek and his sister, Amelia was even more confident that Derek was going to regain his memories.

"We need to understand how far your memory loss goes, but you already know this..."

He nodded, looking at his sister "maybe I can work on it with Meredith, if you want, that is"

"Of course, I took time off f work in order to stay with you" she told her husband "I think you need some sleep first, it's 4 . We'll work on your memory loss when it's not dark outside" she added seeing his eyes grow heavy with sleep.

He agreed without putting up much of a fight, falling asleep almost istantly, leaving Meredith and Amelia time to talk.

"Do you really think he will regain his memories?"

"I'm positive, Mere. Probably not tomorrow, it might take him a few weeks, or months, but you saw the scans as well, the hematoma didn't leave any permanent damage, I'm convinced he will regain his full memory and he will go back to being the annoying hard-headed neurosurgeon we know"

"Okay" she nodded looking at his sleeping form.

"You should get some sleep as well, you look exhausted and I'm pretty sure there will be some really excited kids here around breakfast time" she grinned.

"Yeah, your mom was really happy as well"

"He is her only son..."

"What should I do about Bailey?" she asked as Amelia was leaving the room.

"You should definitely tell him about the little guy... I wish I could be here to look at his face when you tell him, I bet he'll be overjoyed"

"Yeah... I still remember his face when I told him we were going to have another baby" she reminisced.

"The important thing is that he's finally awake. Even if he won't regain all of his memories the important thing is that you'll get to make new ones..."

"Yeah, I know... I had almost lost hope" she confessed.

"Get some sleep, Mere" Amelia gave her a hug and she left the room.

Around seven thirty the following morning Meredith and Derek were busy trying to understand how far back his memory loss went.

"Looks like it's only concentrated in the last three years" she told him.

"With retrograde amnesia that's usually the case" he muttered.

"Hey, no grumpiness..." she tried to cheer him up "we're going to solve this"

"I hope... I can't believe I'm missing three years of my life, of our lives together, of Zola's life..."

"You will get those memories back... it will probably take some time and maybe you won't regain all of them, but you will remember these last three years" she comforted him.

"Thanks for being by my side..." he smiled brightly at her, giving her his signature McDreamy smile.

"I need to tell you something" she added a little while after.

"What?"

"I know you're supposed to try and regain all your memories by yourself, but there is something I really need to tell you..."

"Do I need to worry?"

"No, of course no!"

"Well, do tell me"

"Remember when you first asked about Zola after you woke up?" she was trying to stall, but he merely nodded and she had to go on "I told you that she was okay and she was going to be here with Bailey in the morning, remember?"

"Of course I remember, I only have retrograde amnesia thankfully" he tried to joke.

"Well..." she toyed nervously with her hands, looking at them.

"What is it?" he coaxed her sweetly.

"Bailey is not Miranda Bailey... he's our son" she finally whispered.

"We have a son?" his tone was both excited and disbelieving.

"We do... he's almost two years old"

"And I don't even remember him... what a screwed-up situation" he shook his head sadness feeling his eyes.

"It doesn't matter now, what really matters is that you're awake now and you will get to see them grow up, your memories of him will be back... he looks just like you" she smiled at him.

"Like me?" he paused for a moment, then he went on "does that mean that he's our son, biologically speaking?"

"Yes he is, he's our little miracle" she clarified.

"Wow..." he grinned.

"Yeah, wow" she agreed.

"We have two kids..." he said, the grin planted firmly on his face.

"We do and you were trying to convince me to have a third" she grinned back.

"Sounds like a great idea... if Bailey looks like me we need a little girl who looks just like you"

She burst out laughing, closing the distance separating them, kissing him fully on the mouth.

That's how Carolyn, Cristina and the kids found them, laughing hard and staring into one another's eyes.

"Hey you two, there are two minors here!" was Cristina's first comment, interrupted by two pair of excited feet running towards their parents.

"Daddy!" Zola couldn't contain her excitement as she reached the bed, were her dad was sitting.

"Hi princess!" he grinned at her as Meredith helped her to sit on the bed, the two shared a bear hug and the little girl beamed at her dad.

"I missed you... you slept for a verrrry long time, daddy"

Just as Derek answered his little girl "I missed you too, sweetie" Meredith bent down to pick up Baily and settled him on the bed as well.

"Hey Bailey" he said hello to his son, mesmerized by his features.

"Hi dada" the 22 month old closed the distance between him and his dad to give Derek a sloppy kiss.

Derek felt tears prickling his eyes as he looked at his perfect family, huddled on his hospital bed, he looked into Meredith's eyes and mouthed her "I love you"

"I love you too" she whispered back, just as he spotted his mother.

"Hey ma, you're here as well?"

"Of course I am. Meredith and the kids needed me just as much as you" she closed the distance between the door and the bed and got on the opposite side of Meredith, giving her son a kiss on the cheek.

"How are you feeling?" it was Cristina who asked.

"Like I got run over by a train" he muttered.

"Did a twain run you over, daddy?" Zola sounded concerned.

"No pumpkin, daddy was in a car accident" Meredith placed a hand on her daughter's back.

"Sorry you was hurt daddy" Zola gave him a kiss.

"I'll be okay, baby girl" he reassured her, hugging both of his kids close to him.

So, Derek has memory loss. Don't hate him, this was my plan all along. Him regaining his memories will be a fun ride, so bear with him, I have big plans. Hope you'll leave me a nice review. Chapter five will be posted next weekend.
