Because of shocked and scared after meeting the god Ma Won in the corridor consisting of 2nd and 3rd grade inpatient rooms while waiting for the nurse to return with the doctor to the corridor, Arya even forgot his intention to confirm Alexa's condition at that time.
Then he went back to his room, met his parents, had a fight with them, and ended up just falling asleep. The night was getting late, Jimmy and Nia ate in the cafeteria while Arya didn't touch the food his father bought him this afternoon.
About fifty minutes later, after dinner, Arya's parents returned to Arya's room. Jimmy sat relaxed on the sofa, while Nia packed their belongings and put food and drinks into the refrigerator.
That's when Ma Shin appeared in the room, no one was aware of his presence there. Ma Shin said something about Arya's future, then disappeared in an instant like a flash of light.
