The old dude, Karl's dad, next to Johan in those two shots, is Thomas Hardy. He may have been severely abused while in the care of the hospital... And while in Doctor Michael Reznor's care. Doctor Michael Reznor is one of the culprits. Sexual, physical, psychological, and financial abuse are all possible, whether it is Doctor Reznor, or another staff member. So is attempted murder, and temporary death followed by revival, intentional.
Thomas Hardy was/is a writer and poet.
Good poem by him:
