Alex came in to the O.R. where Amelia and Hunt were working on a crash victim. "Hunt, I just wanted to let you know that both Meredith and Arizona are off duty. It's too hard for them to work on the plane crash victims. There's gotta be a rule. People who have been in a plane crash shouldn't work on one."

"That should be okay. Let April know. We may need to call some other doctors in."

"I know Arizona lost her leg in the crash, but why shouldn't Meredith be working on the plane crash victims?" asked Amelia.

"Didn't Derek tell you about the plane crash?"

"I know Mark died, and Derek's arm was injured. Lizzie gave him her nerves to fix it. I was pretty out of it at the time of the crash. But Meredith was fine."

"Not today, I think. You can get post-tramautic shock even if you're not physically hurt, believe me. The accident was traumatic for her. She lost her sister, Lexie. They were stuck in the woods for four nights, trying to keep Mark , Arizona, and the pilot alive while animals tried to devour Lexie's body. I wouldn't be surprised if this brings back bad memories, maybe even PTSD, for both Arizona and Meredith."

"Meredith and Derek don't talk about it."

"There's a lot they don't talk about."

Later that day, while Owen and Amelia were grabbing lunch in his office, Amelia volunteered, "Yesterday, Meredith tried to warn me off you. She told me that Cristina asked her to look out for you."

"Meredith and I have a complicated relationship. I don't think she ever thought I was good enough for Cristina. She certainly thought I shouldn't have married her when she was suffering from PTSD. And she was right."

"Well, I told her keep out of my life. I told her what I see and what I do is none of her business. That she doesn't know me. She's never lost the loss of her love. She's never cried over the body of the person she loved the most. Until you've had to walk in my shoes, she needs to cut me some slack."

"You told her that she hadn't lost the love of her life?"

"Right, she has Derek."

"You really don't know Meredith at all. What did Derek tell you about the shooting?"

"He told me that Cristina saved his life."

"She did. With Meredith's help. They both were in the hall when Gary Clark first approached Derek. They saw him shoot Derek, and they ran to save his life. They got him into the OR."

"And he survived."

"You don't know what happened in the o.r., do you?" Owen said. Amelia refused to meet his eyes and continued looking at her food.

"I know Cristina saved his life."

"Yes, with Gary Clark holding a gun to her head. I walked in the O.R. and saw him there. Cristina had asked Meredith and April to wait outside, but Meredith saw me go in and followed me. She saw Gary Clark threatening to shoot Derek again, while he was on the table. I will never forget what she did. She told Gary Clark to shoot her, not Derek. That if he wanted an eye for an eye, if he thought Derek killed his wife, he should shoot her, not Derek. And then Derek flatlined, and Meredith thought he was dead. She was totally destroyed."

"But Derek survived."

"Because Jackson had removed the leads so it looked like he flatlined. Meredith thought he was dead, which made it completely believable to Gary Clark, so he moved on and left the room. Then Cristina finished the surgery. I'm sure Meredith will never forget what it felt like to see Derek die."

"I didn't know. And Meredith didn't say anything."

"Just like she doesn't know you, you don't know her. And, although Meredith and I have our differences, there's no question that she loves your brother."

"That I know. They've been spending a lot of time reconnecting, loudly. I wish Derek had soundproofed their bedroom."

"You can always stay with me."

"Sounds like a good idea," said Amelia with a smile.
