Hunt, George and Cristina are examining GSW guy (who never gets a name, so that's it from here on out) and Cristina is getting increasingly aggravated as Hunt ignores every suggestion she has and works exclusively with George. As they work, he tells her to page Shepherd, which she clearly thinks is a job someone else should be doing.
Arizona, meanwhile, is checking about Maddie and asks her how she got a big cut on her cheek. Maddie still hasn't said a word but her mom, Kate, gets up and tells everyone that Maddie is scared that they are going to take her away because she did a bad thing. Richard tells her that the police want to ask about Maddie's cut, and Arizona adds that social services will be there to give them the support they need and that no one will take Maddie away. Kate seems to think a moment and then blurts out that the kickback from the gun caused the cut. Arizona seems suspicious so Kate jumps in to add that her husband shoots targets in the backyard (I know it's how I love to spend a glorious weekend day) and just put the gun down a second, which was really stupid. (Duh.) Maddie still says nothing, and Richard assures them that it will be okay. This girl is really cute, but as child actors go she's not the most convincing tragic moppet they've had on the show -- she really never changes expression throughout the entire episode and seems a bit like a really cute zombie. And I don't think that's an acting choice to go along with the story.
Thatcher reads his letter of apology from a notebook, telling his daughters how he's sorry for every time he ever hurt or disappointed them, or let them down. Mere's face is still stony, and she taps her foot impatiently while next to her, Lexie is on the verge of tears. Thatcher wraps up by telling them he doesn't deserve their forgiveness, but he hopes they will give him the opportunity to earn it. I've never been a big fan of Thatcher, even though I realize Ellis was completely horrible to him, so I'm watching this scene kind of like Meredith is right now. Lexie starts to crumble but Meredith just looks at him with arched eyebrows. He tries to smile at her but she just stands up and thanks and congratulates him. She tells him, not in a mean tone, "You seem well. Good luck," but still leaves right away. As she walks down the hall she turns back and sees him and Lexie embracing in the office.
Izzie's mom, Robbie, is chatting away about all of their neighbors, telling Izzie about how one of them had breast cancer and what a shame it was since she had such a good rack. Izzie looks completely exhausted, more from her mother than the cancer, I think, as Robbie jokes that she had her breasts cut off to be safe and they look even better now. "Life gave her lemons, and she made cantaloupes!" You can already tell that this is the mom you'd want to go talk about boys with after school, but who you might not want to have as your actual mother -- don't get me wrong, she seems lovely and well-meaning, but not motherly. Izzie tries to explain her illness but when her mom hears the words "skin cancer" she breathes a huge, dramatic sigh of relief that it's just a little old mole. She can't believe she was called just for that, while Izzie can't believe she was called at all, and looks from Bailey to Alex demanding to know who called her. They both look possibly guilty, but neither says a word.
