Maddy is prohibited from seeing, or even contacting, Olly. Even though her mom limited her use of technology, Maddy communicates with Olly through her window with paper.
I want to go to Hawaii, it was the last place I had my entire family was together. I have money, we should leave soon.
It's fine, I'm fine! It's a legitimate medicine. I can live, Olly!
A new Nurse is assigned to Maddy by her mom. She hates her new nurse, who is all work and no remorse, continuously taking Maddy's vitals and watching her every move. Maddy plans a getaway with Olly to secretly see the world.
Olly wants to keep Maddy safe, but she persists that she needs to go on this trip to see the world one last time. She devises a plan to buy tester medicine online for SCID, and tells Olly that it works. She was willing to lie to make Olly happy and to go on this trip.
I will. I love you, too, Carla.
Please be careful. For me...
Alright. I'll take some of my dad's money, we'll leave tomorrow.
Olly is skeptical about the medicine, until Maddy says it was prescribed and not bought. Olly finally agrees to go, and they plan to take some of their parents money as well as Maddy's money to leave to Hawaii for a week.
Maddy and Olly leave, but Maddy has them stop at Carla's house before going to the airport. She is ready for whatever consequences there are for leaving her sterile environment, and says goodbye to Carla, possibly for the last time.
Carla can tell that the pills are fake, and tells Maddy to be extra careful. After a sip of water and a little break, Maddy and Olly leave for the airport when the taxi comes.
