Izzie walked into the hospital and could feel the eyes of everyone around her, filled with pity. She sighed and trudged ahead. She had never been one for pity, sure, she had always wanted people to understand when she was hurt and be sensitive, like when Alex had slept with Olivia, but this, this all encompassing pity, as though she were some poor mutt with no family and no home was more then she could take. She lowered her head, willing herself to keep moving until she reached the ER. When she arrived, she saw George and Meredith bent over a hospital bed, attending to a patient and she caught a glimpse of dark hair cushioned by a pillow, before Bailey grabbed her arm and steered her over to one of the other beds.

"Stevens, we need you over here, you're working with me" Both doctors stopped in front of another bed, and Izzie picked up the patient's chart.

"Male, late twenties, driver of the car, broken leg and arm" She turned to Bailey,

"Do we have an ID?" The older doctor shook her head,

"No, they were too unstable in the field for the EMTs to risk looking for one, and all three patients have been unconscious since arriving, so they're no help, look through his stuff, see what you can find. I want you to keep an eye on him, he flat lined, see that it doesn't happen."

"Just one patient? I can help with the other two if you want" Bailey looked at Izzie with sad eyes, and Izzie was struck with awe that she looked at her with anything other then disgust.

"No, Stevens, ease your way back in, don't get in over your head. He's being transferred into his own room soon, wait with him, see if he wakes up, when he does, try and get some info." Izzie nodded and bent over the patient, listening to his heart with her stethoscope and Bailey turned to join Meredith and George at the other patient's bedside.

"How's he doing?"

"Okay, we called for a couple of tests and Sheppard's coming down for a consult on the possible brain damage" George informed his resident, he glanced over at where Izzie was still listening to her patient's heart and he leaned in closer to Bailey to whisper in her eye.

"Don't you think this is a little weird? I mean, look at the guy"

"I am, O'Malley, and all I see is a patient that needs our help. We can figure out all the weird stuff afterwards"

"But he never mentioned anything about any brothers or any family members at all" Bailey glared at George.

"What did I just say? Weird stuff later, right now take the patient up for his tests" George nodded, chastised.

"Grey, where's the other patient, the one with the collapsed lung?"

"Cristina and Alex took him up to surgery to repair the lung, Dr. Weber's performing it"

"Alright, good, Stevens is going to stay with the third patient, see if she can get a history or ID"

"Okay" Meredith nodded, something in her tone alerted the resident to the fact that she obviously had more to say. Bailey sighed.

"What is it, Grey?"

"Should we tell Izzie? I mean, this is unbelievable, her first day back and this happens"

"And what will we tell her? We don't even know what's going on, wait until we know more, then maybe we'll tell her" Meredith nodded, satisfied with the answer and helped George wheel the patient away.

A groggy voice broke through Izzie's mid fog, and she quickly glanced over at her patient. He looked to be about the same age as Izzie but with his brown hair matted with blood and his handsome face crisscrossed with scars and bruises, it was hard to guess his exact age and as Izzie watched his eyes fluttered open.

"Sammy? Dad?" The blonde doctor went over to the man's bedside, and began checking the monitors.

"Sssh, don't over exert yourself, you were just in an accident" The man struggled to raise himself up on his elbows, but Izzie pushed him gently back down onto his mattress.

"Where am I?" he asked, eyes glancing over his unfamiliar surroundings.

"You're in a hospital, Seattle Grace; you were airlifted here after your accident"

"Seattle? But we weren't anywhere near Seattle."

"I know, but the EMTs decided to bring you here, it's one of the best hospitals in the country." The man grimaced and Izzie moved towards his morphine drip, prepared to administer more if he was in any pain.

"Are you in pain?" she asked gently.

"You could say that, I hate hospitals, give me bad memories" The man looked at Izzie finally, glancing over her face appreciatively, a slight grin pulling at the corner of his mouth.

"You don't look like a doctor" Izzie looked down, she couldn't handle flirting with anyone, especially not a patient, the last time she had done that, things had ended worse then she could've ever imagined.

"I get that a lot" She moved to grab his chart and examined it closely, careful not to look back at the patient's face.

"So, we ran a few tests on you to make sure there was no internal bleeding or organ damage and we noticed that there was some scarring on your heart, what happened there?" The man groaned and leaned his head back, closing his eyes. He put his hands over his face and said finally;

"I knew that was gonna come back and bite me in the ass. I had a heart attack a while ago, a pretty big one"

"And you made it through?" The man snorted, as if remembering a particularly funny memory.

"Yeah, my brother Sam called it a miracle" Izzie looked back up at the patient finally,

"Your brother? Was he the other young man in the car?" The man nodded, grimaced and laid a hand on the back of his neck.

"And the other man with you, who was he?"

"Our dad" He raised his head suddenly, as if struck by a thought.

"Wait, are they okay?" Izzie searched her memory, trying to remember what she knew about the other two.

"Your brother had a collapsed lung and your father might have some head trauma. Your brother's in surgery and your dad's getting some tests done."

"But are they okay?" The man's voice was frantic and was laced with over protectiveness. Izzie could see it in his eyes, this man was used to taking care of those around him, and this helplessness, leaving those he loved in the hands of someone else was probably more painful then his injuries, and Izzie found herself connecting with him, but quickly shook it off. She would be nice, of course, but she wouldn't let herself relate to her patients or get too close anymore, that road only led to heartbreak

"They're fine" Izzie soothed, "As long as there's no serious damage to your father's head, you'll all make a full recovery."

"Alright" The man nodded, seemingly satisfied. He laid his head back against his pillows and closed his eyes. Izzie remembered suddenly what her purpose here was.

"Um, I was wondering if you could help us" The man opened his eyes and scrutinized Izzie carefully.

"Me? Should I be worried that my doctor's asking me for help?" Izzie shook her head, a forced smile on her lips.

"Not even a laugh, huh? I must be losing my touch." The man's eyes glittered playfully and a lump rose in Izzie's throat, she could feel tears rising to her eyes, but stubbornly pushed them back.

"We weren't able to find an ID on either you, your brother or your father and we'll need some sort of identification to get a proper medical history." The man sighed, obviously none too eager to over share, clearly hiding something. Izzie sighed.

"Listen, I don't care if there's some deep dark family secret hidden in your past, we need to figure out who you three are or we'll have to turn the case over to the police and they figure it out." The firm tone in Izzie's voice was one she rarely used beforehand, but she found herself calling on it more and more in the last three months. The man sighed in resignation.

"Fine, I'm Dean, my brother's name is Sam and my dad's is John" Izzie wrote the names down on a pad of paper.

"Last name?" Dean sighed again,

"Winchester"
