Sebastian got back after a brief discussion with the attending doctor. Apparently, Kylie's father's recovery was progressing well until they met someone while taking a walk in the big garden in front of the hospital.
According to the nurses, they saw someone approach the old couple and talk to them about something. After that person left, both the couple's faces became pale. All of a sudden Mrs. Johnson collapsed and by the time the nurses reached them, Mr. Johnson had another heart attack.
Everything seemed too confusing to Sebastian. He deliberately lied to Kylie. Last time Doctor said she was depressed for some reason so he didn't want to worry her more about her parents. The doctors will take care of them. Also, he appointed two guards to keep an eye on everyone coming to meet them.
