Ending Theory - 'I'm Jack' (SPOILERS)
I just watched The Ruling Class from beginning to end for the first time yesterday and loved it, but the final scene had me wondering something.
After Jack has stabbed Grace and the camera pulls back from the house, we hear Grace's inhuman scream - mirroring the one Jack had made ten minutes earlier - followed by a boy saying, "I'm Jack. I'm Jack. The captions suggested that the speaker was their son, the future 15th Earl, but I have to admit, I actually think it may have been Jack himself.
All throughout the film, his sanity goes from one extreme spectrum (God) to another (The Ripper) with no in-between balance. All the characters suggest that Jack had a somewhat normal childhood. Then the last scene/shot left me thinking that couldn't be the baby speaking. He was far too young to start speaking, let alone know his first name. Perhaps with the murder of Grace - the only person who truly loved him for who he was - the act had caused Jack to have one final meltdown and leave him stuck in the infantile state of mind where life was an actual life and not an extended grooming period for induction into the House of Lords.
We will be cruel to the Germans, and through our cruelty, they will know who we are.
