A girl walked into the room with the words 'dr. John Armando' stamped on the surface of the door. He entered without knocking on the door. Of course, he didn't need anyone's permission to enter or leave the man's room.
No, no. He was not a special guest that John had deliberately summoned, but a guest who did have access to visit regardless of whether the man was on duty or not. Someone who had just a few days claimed to be John's special friend.
Of course all of that had been validated by that man. Making Clara a special friend doesn't seem to be a difficult thing. Their meetings are not just one or two times but often. If asked because of what. Of course it is because of fate.
However, many things from Clara that he was worried about would actually thwart the plan he devised. More precisely, they arrange together. It could be clara changed her mind, or be careless to make all the misery.
