Alex's Dad name is Daniel.
Daniel: Hey Miss, you are a doctor?
Izzie: yes, Mr.Karev I am, I will be your doctor for the night.
Daniel: Oh ok, your name is Isobel.
Izzie: Just call me Dr.Stevens.
Izzie just checks all the machines and his heart rate.
Daniel: Why can't you look at me?
Izzie remembers that Alex's father beat up his mother, so she didn't want to make any kind of relationship with him.
Izzie: I am your doctor, that is all.
Daniel smirked, like Alex's smirk.
Izzie turns her face when she saw it.
Daniel: He told you huh?
Izzie: What?
Daniel: You know my boy Alex, he told you I was a drunk/druggie who beat up his mother right?
Izzie: Sir, let me just make sure you are ok. Ok?
Daniel: Yeah, but yeah you saved my life, so I want you to know something.
,
Izzie: Okay.
Daniel: Well, Ms.Stevens, don't get me wrong I am a horrible husband, horrible father, and even probably a worthless person. And I want a chance to change that.
Izzie: A chance? Don't you think it is too late for that?
Daniel: Yes, but I need to, I have been sober and drug free for 10 yrs. I have reconciled with my ex-wife and daughter. But not Alex, I don't think we ever will , but I have to try. You know?
Izzie: No I don't.
Daniel: I am going to die, I am dying, I fucked up my livers and all my organs, and I just wanted to die knowing my son does not live in anger because of me. I want him to be free of that anger. Because I wasn't I lived with it. And it ruined my life, my family, me. I need a chance.
Izzie started to get tears. She knew Alex's dad had a huge effect on Alex, but she needed to give him a chance, because if Alex had no more anger from his Dad, she knew that would help him. Although Alex changed he changed without his Dad.
Izzie: Okay, everyone deserves a chance, but let me tell you this first. Alex ,he is a wonderful doctor, he wants to do plastics, but I know he is going to go into peds, or something with children. He loves children even though he tries not to admit it. He used to be an ass, yes, but he changed. And I don't know what changed him, but he did. He can say the most vulgar things, but he always comes off charming you in a way, I cannot explain. He has the same smirk you have, and he is very smart, did I say that. He failed one of his boards and he had to retake it. He was able to be an intern and pass a board exam. Like seriously, how is that even possible. He has this half-smile which most people cannot pull off, but he can. He has this way of making you feel better, even if you think he is an ass most of the time. Alex is a wonderful guy. I just want you to know, that he would be ok, even if you did not try to reconcile with him.
Daniel nodded his head in tears.
Daniel: And you love him.
Izzie stared at him for a bit, she did she thought to herself, she is in love with Alex.
Izzie: Hey lets try moving your arms.
And that night Izzie and Alex's Dad stayed up talking all night
