He is still not ready to recover those memories.

In the previous chapter, we read that Robert remembered something when he heard the sound of Azan then he blacked out. Robin hold him in his hands and Mr. Henry ordered the driver to take the to the hospital. They took him to the same hospital and the doctors took him to the emergency room, everyone sat outside waiting for him and was devastated. After a while, the same doctor, Dr. David came out of the room. Mr. Henry stood from the chair and asked:

Mr. Henry: What happened to my son?

Dr. David: Come with me!

Mr. Henry, Mrs. Henry, and Robin followed Dr. David to his room. When they got there Dr. David said:

Dr. David: Have a seat, please!

They all sat on their seats then Dr. David started explaining:

Dr. David: So, as I told the warden and this kid. He has had memory loss due to a severe accident. He is still not ready to recover those memories.

Mr. Henry: What do you mean?
