A/N: Hey you guys! I'm back with a new story, this one is based on the movie "The Family Man" (Kate Walsh has a small role in there) you don't really need to see the movie to understand this because it's all explained in this first chapter. The thing is that there was a story like this one here on this website, but it was deleted by the author, I was looking for that story and when I realized that it was deleted I wrote my own version of it, I really hope you like it

What if you made different choices? What if you say "Yes" instead of "No"? What if you got a second chance? - The Family Man

For Derek Shepherd, this has been one of the best days of his life, he couldn't even describe the way he was feeling, after all those years working in the Seattle Grace Hospital, he was finally getting the job he always dreamed, he was gonna be the Chief of Surgery of the hospital, since Richard announced his retirement, he was the first and only candidate for the job, and he knew he was the best to do it, everybody knew it.

Now he could say he had everything he always wanted, he's been married with Meredith for now two years, via post-it, but still married, they weren't the perfect couple anymore, but they were still together, and now he was actually getting the job he always dreamed about, for him it was like a dream come true.

To celebrate this achievement of Derek, Mark planned a party at Joe's, with all the people who worked at the hospital, so they could say goodbye to Richard on his last day as the Chief and say hello to Derek as the new Chief. Derek at first didn't want this, he just wanted to go home and be there with Meredith, but celebrate this occasion with his friends was good too.

When he arrived there, he wasn't feeling the way he expected, he knew there was something missing, but he just didn't know what, all of the people he works with everyday are there, why would something miss? He figured this feeling would quickly pass, but it was actually bothering him all night, that he couldn't enjoy the party as he expected it.

Every time that someone approached him, he just smiled very distantly, not because he wasn't interested about what they were saying, it was because he was trying to know what was missing there and he couldn't just let it go until he knew. When the party was about to end, Mark sat next to him in the table where Derek was with a scotch on his right hand, which he drank everytime he started to think.

"What's wrong with you, man? We are all here together, happy for you and you have spend all night sitting there, getting drunk and not talking, is there everything okay?" Mark asked to his friend, he knew him to well to know that he wasn't fine. "I'm fine" He simply said drinking another shot of his scotch.

But after Mark left, Derek quickly got it, he knew what was happening to him, he remembered the words Richard once told in one of the conferences of the hospital, "The biggest influences in your life are sitting around you, right now" he realized that one of his biggest influences wasn't there, the woman who helped him to be the surgeon he is, and has been with him in every fall of his career, well until 4 years ago that it was the last time he saw her. His ex-wife, Addison was the only who helped him to go back to work the next day after his first patient died, she was the one who listened complaining about how mean was his resident, not letting him scrub-in when he was an intern, she was the one who was there, watching him in the gallery, when he did his first craniotomy and realized he wanted to be a neurosurgeon, she was the one who celebrated with him the moment he got in the neurosurgery fellowship, she was always there to support him, in his goals and his failures. But tonight, she wasn't she was the person who was missing in this moment of Derek's life.

After everyone left Joe's, even Meredith, Derek was still there, thinking that without Addison's help he probably wouldn't be there right now, about to be promoted as the Chief of Surgery of the hospital. He was too busy with his thoughts that he didn't even realized that Richard was still there, so he just smiled at him a kept doing what he did all night instead of celebrate, but Richard knew that look on Derek's eyes and decided to sit next to him.

"So, the party was really good, uh?" Richard started, Derek has been like a son to him and he hated to see him like this, especially in a day when he should be one of the happiest days of his life

"Yes, it was" Derek simply answered him.

"I can't believe that I'm finally retired, it's good to know that I'm gonna have more time to myself and spend it with my wife, Adele is the one who's more happy about this, though I really gonna miss all of you, being the Chief really changed my life, I can't believe that part of my life is over now. I'm sure you'd do a great job, I'm really glad that you are the one who is taking my job, I really can't imagine giving it to anyone else"

"Thank you, Richard, I know that is not an easy job, but I'm really happy that now I can finally have the job that I've worked so hard to get" Derek said, still with a half-glass of scotch on his hand.

"Well, now I see that my work as your mentor is finally done, you're one of the best students I've ever had, at first you really didn't like me" They both laugh "But you turned out excellent, Shep. I'm really proud of you" The old man confessed putting his hand on Derek's shoulder in sign of friendship.

"I was lucky to have you as a mentor" And to have Addison by my side supporting me, he wanted to add, but he new that Richard wouldn't take it that well if he says that.

"So, you have everything you wanted, I don't know why you don't seem like you do" Richard told him, noticing that the look on Derek's face changed with those words

"I don't know what you're talking about, I do have everything I ever need, since tomorrow I will be the Chief of Surgery of the Seattle Grace Hospital, I have friends who support me, why would I ask for more?" He said now a little angry.

"And a beautiful wife who has supported you in every step of your way" Richard complete Derek's phrase

"What does Addison has to do with this? She's not here, she has been with me since the very beginning of my career, but now she's not, that's all" Derek said without thinking

"I'm not talking about Addison, Derek. I'm talking about Meredith, I said wife, no ex-wife. Are you sure you have what you need?" Richard said slowly, now getting Derek's attitude

"Of course I am, like I was saying I have everything I've always wanted, I have the job, my friends and, uh, Meredith" He said trying to fix what he said before.

"Okay, Shep, remember that you brought this on your own" Richard simply told Derek, taking off his hand the glass of scotch on Derek's hand and giving it to Joe. "Don't let him drink more Joe" The Chief said turning to Joe.

"What do you mean with 'I brought this on my own'" Derek said air-quoting

"Oh, that's nothing, you'll find out" Richard said smiling, turning back at Derek "Joe, don't let him drive, call him a cab" He said to Joe and left, Derek wasn't sure that he was getting the whole point of Richard's conversation, but he was almost sure that the alcohol has something to do with it he decided to not pay much of attention and wait for the cap that Joe was gonna call him.

"Joe, do you remember Addison, right?" He asked the bartender, Joe clearly knew that this was the alcohol talking, but after running a bar for more than 10 years, he was really used to deal with this kind of situations

"Of course I do, your beautiful redhead ex-wife" Joe simply said with a smile on his face while he was cleaning an empty glass

"Do you think I was stupid for letting her go?" He asked like if Joe knew all that he went through with Addison

"I think that you two moved on and turned that page a very long time ago"

"Yeah, I know, especially me and Meredith, you know that you're the only person I can talk about this and I know wouldn't judge me" Derek knew that he wasn't that drunk, he just wanted to hear an impartial opinion.

"Yeah well, you know another person who wouldn't ever judge you? You're cab driver who's outside waiting"

"Thanks Joe"

About thirty minutes later, he arrived to Meredith's house, he was expecting that after he'll come, he was just gonna sleep until tomorrow to start his first day as a Chief, but what he didn't expect was that Meredith was waiting for him in the living room, something that she had never done before, she looked serious, maybe she was mad at him because he stayed at Joe's until everyone left and for the fact that he was drunk

"Derek, you're finally here!" Meredith exclaimed at the moment she saw Derek coming from outside "I tried texting you and calling you but apparently you've turned off your cell phone"

"Yeah, well here I am, why are you here alone in the living room?" He asked

"Because there's something you need to know, please sit down" Meredith said calmly while he sat next to her "First I need to know if you're under your five senses, because if you're not we can talk about it tomorrow"

"Yes, I'm good, I'm not as drunk as I look like, tell me, what happened? You're starting to scare me" He said to her, normally when he comes home late at night Meredith is already sleeping in their room, or talking with her friends who also lived there, but she had never seemed so serious and a little bit afraid before.

"Addison called" She simply said, Derek felt like this is the first day in months that he decides to think about his ex-wife and this exact same day all the people he knows seems to be a mind-reader, now Meredith was the third person who named Addison in the same night

"Like my ex-wife, Addison?" Derek asked, knowing the answer already

"Do we know any other Addison?" Meredith responded sarcastically "Anyway, she wanted to talk to you about something, but I told her you weren't home"

"Well, I guess I'll call her late this week, it's not like we don't have a live of our own to be worried if my ex-wife calls me or not"

"Derek, she wanted to tell you that her mother just died in a car accident"

"Oh my God" Derek couldn't find any other words to say, he was never a fan of Bizzy, but the woman always told him he was the right guy for Addison, and he knew how much she used to criticize her, but there was something about Bizzy that made her impossible to hate.

"Were you two close?" Meredith asked him curiously, she didn't expect that Derek would take this so bad.

"Well, she used to love me when I was his son-in-law, she used to tell me that I was like the son she never had, which is funny considering that Addison has a brother" He said with a sad smile on his face

"I'm sorry, Derek" She said holding his hand "You should call her" She said to him and left the room and went upstairs.

Derek took his cell phone and turned it on, he saw that he had text message from Meredith, Mark and this announcement "You have 5 missed calls of Addison Montgomery" She had to be really desperate to call him that much, knowing that they haven't seen each other since she left the city.

Derek quickly dialled her number and waited until she took her phone

"Derek?" He heard Addison, her voice sounded sad, which it was obviously

"Addie, I just found out, Meredith just told me, I'm so sorry"

"Thanks, I thought you should know, I wasn't really gonna tell you, but Amelia convinced me to"

"Thanks for telling me, how are you doing?"

"Can I be honest with you? I know you're the only person who can really understand me"

"Of course"

"I don't feel anything, I know it sounds cruel, but I just don't feel anything about it, the woman spent her life making my life miserable, until her last day, she cheated on my father with Susan, Do you remember her? Then I had to save Susan's life, my mother's lover and Bizzy didn't even say thank you" She started to cry and Derek was trying to stay strong "She was my mother, but she never was my mommy, now I don't even have a chance to get to have a better relationship with her" Since she found out about Bizzy's death she haven't cry, she had a feeling that there was something missing inside of her, but she didn't cry, and now she has two words with Derek and she starts to let out how she really felt about Bizzy "I know she wasn't the perfect mother like yours, but I really loved her, even when I always thought she didn't… I'm sorry if I'm bothering you, Derek"

"No, no, no, it's okay honey, that's why I called you, I get all that you're feeling. Where is gonna be the memorial service, I wanna be there with you?"

"It's in my parents' house in Connecticut, well, The Captain's house- I think Amelia told your family and some of them are coming, you don't really have to go there, I know that you have a lot of patients and probably Meredith wouldn't like it"

"I wanna go there"

"Thanks"

"Well, I guess I'll see you then, try to get some rest, I know you need it"

"Okay, thanks Derek, Take care"

"Bye Addie"

Just after he hung up the phone he immediately texted Amelia, she lived with Addison and he knows how much she loves her "Please take care of Addie for today, I'm going to Connecticut tomorrow, I'll see you there xx"

After all of this, he stayed in the living room, remember all of the moment he shared with Bizzy, until he felt sleep there, he knew that we would have to talk to Richard to tell him about Addison's mom, he would understand.

But went he woke up the other day, he realized that there was something different since the moment he opened his eyes in the morning, he woke up in a very organized and nice bedroom that wasn't his, suddenly the door of the room was opened by a 5 year-old, black haired with blue eyes exactly like his.

"Daddy! Wake up! You have to take me and Katie to school" Derek was almost sure that he was dreaming, this couldn't be happening there was no logic at all in this, and to make this even crazier, Addison walked in there, wearing pyjamas and with a very messy hair.

"Christopher, how many times do I need to tell you that you can't wake up your father like that, he was on-call last night" She actually said that word, apparently I'm the kid's dad? Derek thought while he was looking all this

"I'm sorry mommy, I just wanted him to take us to school" The little boy said with a sad face

"Okay, just go and take your sister to the kitchen, I made pancakes"

"Yaaay" The little boy left his parents alone while he was gonna do what his mother said

"Honey, I'm sorry he woke you up, but you know how excited he gets when you take them to school"

"Addison? Why am I here? Last night I was in my living room, at Meredith's and now I'm here?" He said out loud, maybe sounding crazy, but maybe she could explain this

"What are you talking about? Honey, I didn't know you were that drunk last night, I guess I blame Sam for that" She said kissing him in the lips "Let me refresh your memory, Mr. Hangover, you went out with the guys last night and Amelia, Naomi and I stayed here with your children"

"What about Bizzy?" He asked, is Bizzy dead in this weird universe too? He asked to himself

"Did she call or something?" Addison didn't know what he was talking about

Well, apparently not, he thought, he had no idea what happened, he didn't know if he was dreaming, but he knew that it was gonna be a very long day.
