Claire talks about the first time she met Shaun. Shaun interrupts that pancakes are ready, Lea tells Claire that Sophie has put together wedding planning books for them. Lim shows up with coffee for Claire. Sophie reveals that Claire has been offered Chief of Surgery in Guatemala.  It's time for Lea to go do wedding stuff.

Claire's plus 1 is a kid who needs hospitalization. He has massive tumors.

The kid has not had access to medical care and tumors have been growing for years.

Meanwhile Lim has to deal with a patient who is crashing. The nurse on duty discovers Nurse Villanueva did not give the patient his required meds.

In the limo, Lea still hasn't chosen a theme. She doesn't seem to like any of them. Finally she finds an upscale elegant theme she likes.

Shaun is looking at photos of rings while the kid is in the MRI. He thinks Lea would rather a new computer. Lim arrives and Claire again asks if Lim think she would be a good chief of surgery. Lim tells her she has to be prepared to put her emotions aside on difficult days.  Sometimes you have to be a hardass. Shaun settles on a ring that Lea can sell to get two laptops.

The imaging shows a tumor in the heart and brain.

Andrews has assembled three teams. Shaun is on the brain surgery team with Glassman. Lim needs someone to oversee all three teams. Claire volunteers. Lim is hesitant but Claire insists.

Sophie plans to use seat fillers since Shaun has no family. Lea's parents will have a first class flight and be on camera at the airport.

Park and Andrews practice for the kidney surgery.  Park asks Andrews about his wedding present. Claire interrupts. They need a better plan than removing the kidney altogether as dialysis is hard to come by in Guatemala.

Morgan has a non-surgical intervention idea for the heart. They need to do the heart surgery anyway.

The nurse tells Lim she had a bad night with her abusive boyfriend. Lim is putting her on administrative duties and expects her to call a women's shelter. The nurse says it's complicated. When her mom died she was alone and that's when she met Owen. Lim says it's hard but necessary for the nurse to leave Owen.

During the brain surgery, Shaun asks Glassman what he should do about the suit Lea wants him to wear which he doesn't like. Glassman says he would never wear such a suit. Maybe if he had he wouldn't have been divorced. The patient starts having seizures.

The brain tumor needs to be removed. Andrews argues the kidneys should be first. Morgan agrees and says they have a technique that will help the kid recover. Claire says if there's a chance the kid can play soccer she wants to take it. Kidneys today, brain tomorrow.

Lea picks a dress. Jordan wonders if it really fits Lea's personality. Lea says this more than just their wedding.

Park and Morgan have a veiled argument about the breadmaker. Asher and Jerome also had an argument over whether they should wear matching suits. The kid starts crashing. They need to take the kidney. Claire calls them to stop. She is able to resolve the issue without having to remove the kidney.

Lim tells Claire that Guatemala has turned her into a 5 of the hardass scale. But she doesn't think Claire is ready to be chief. They shouldn't have gone with kidneys first. Claire says she is considering quality of life. Lim tells her her nurse is having problems. Claire says she always admired Lim, but she's not sure she does anymore.

Shaun has made huevos rancheros because they are Lea's favorite even though he hates them. Lea tells him if he wants to wear a different suit it's okay. He says he is okay with it and tries to force himself to eat the eggs.

Nurse Villanova decides to give Lim her resignation as she can't make herself call the shelter.

Shaun is getting his wedding suit fitted while talking about his plan for the brain surgery. He begins freaking out. They get called in to the hospital. Lim says the kid has a bleed in his brain. He now has a blood clot interfering with the tumor. Shaun says Lim was right. Clearing the clot will take 4 months but the kid will die in three of the tumor. Shaun tries and fails to visualize a solution

Claire breaks the news to her patient that they are going home and she doesn't know if they will come back for more operations. Shaun comes around the corner.

At the bachelor party, Shaun is still trying to figure out a way to save the child. He thinks he will fail as a husband. Claire says love isn't measured by accomplishments.

When they arrive, Glassman tells Shaun he doesn't have to do this. Shaun stares at a neon sign and gets an idea about how to get around the blood clot. He and Claire hurry back.

The little boy is scared. Claire hugs him.

The boy wakes up after the operation. Claire gives him a soccer ball.

Claire tells Shaun she's happy and sad. She's happy for him and how far he's come and sad because she misses him. He missed her too. They hug. He needs to go. He's getting married in five hours and doesn't know what he's going to wear.

Jordan helps Lea with her veil.

Morgan says that Lea and Shaun are the cutest couple ever.

Asher ships Shaun and Lea. He also apologizes to Jerome for the matching suits.

Shaun comes to see Glassman. He has a bow tie and the jacket which he says he's been practicing wearing. He can do it for 44 minutes. If he skipps the redundant parts of his vows, he can make it.  Lea shows up and says they need to talk.

At the church, Lim is not accepting the nurse's resignation and wants her to come live with her.

Lea feels Shaun shouldn't put himself through torture to marry her. The camera crew comes in and Lea says the wedding is being postponed because this isn't really them.

Claire is heading home. Lim thinks Claire should take the Chief job.
