Alexander apologizes. Cuevas takes him to the vending machine so Charles and a resident can talk to the grandmother. She has broken a hip and has weak bones. She says she has stage 4 lymphoma that she has decided not to treat. She might only have a few months. Alexander doesn't know. Charles tells her she needs surgery for her hip. She doesn't want it as she has to take care of Alexander. It's always been just him and her. No one she knows wants to take him on and she's the only one who can calm him down. Alexander returns and asks if he can have some type of junk food.

Marcel says he can reconstruct one but it will be complicated and he thinks it's too risky. Roy doesn't know how much longer he can go on like this. Dr. Duvrey has overheard and wants to use 2.0 for this. Marcel says no. Duvrey says this is the perfect test case for 2.0 (didn't that happen already with the last surgery?)

Archer asks a nurse to inform the police. Lieu says he has experience with search and rescue. Archer lets him go look and asks Asher to help.

Duvrey uses 2.0 to create a hologram that Marcel can practice surgery on. He is skeptical. Duvrey says 2.0 can imitate what will happen during Roy's surgery. She convinces Marcel to give it a try.

Will runs the test on Sophia. It shows she has the syndrome. She needs a pacemaker and will have to avoid swimming for 6 weeks, but that will stop her from competing.

The search begins. The sheriff has brought a drug sniffing dog in case it can find the pregnant woman.

2.0 says the reconstruction is impossible. Duvrey asks it for the prognosis. 48% chance of success, but 2.0 is programmed to deny surgeries with less than 50% chance of success. Duvrey overrides the setting and 2.0 tells Marcel how to do the surgery.

Alexander says he doesn't know what happened and doesn't remember eating anything strange. He says he doesn't eat anything without Grandma's permission. He says Grandma opened the surgery.

Marcel does the surgery. He finds the small bowel may be better. 2.0 says no. Marcel disagrees and decides to remove the esophagus.

Will thinks Jack might be able to help as she is a fangirl. Jack says he has a plane to crash. Will says why did you buy the hospital if you don't care about the people in it? He storms off.
