Corrected entry: Why the would cleaning company hold Kate responsible for her equipment? Surely they'd have listened to her story and sent Leonardo the bill since he threw it overboard.
Corrected entry: No keys are in the ignition when coming home from the hospital.
Correction: Plenty of modern cars have keyless ignition, where the key just needs to be inside the vehicle somewhere, then you press a button to start the car.
Corrected entry: Leo's dad and sisters could not know where Kate's house was in order to find him.
Corrected entry: Eugenio Derbez is a rich and very famous person in the world, it's impossible that nobody recognizes him in the hospital.
Correction: This is a question, not a plot hole. The company may have loaned the employees the equipment under contract that employees are responsible for any damage or loss. In which case, they can go after the employee (which is much easier for a few reasons). It would then be up to Kate to go after Leo for any costs she sustained because of his actions. She may also have been an independent contractor and bought the equipment, in which case, she would be the party responsible for going after Leo.
