In the realms of fan theories concerning the world of Christopher Nolan's stunning Bat-trilogy, this upcoming one is a ton of fun, and would've been absolutely insane if it were true! But despite my musings it's up to you to open your mind to the theory that Joseph Gordon-Levitt's John Blake could, in-fact, be the son of Heath Ledger's Joker.
The Joker - Special Ops or Spy?
hokky posits that, seeing as the Joker is a master tactician, has formidable hand to hand combat skills and is knowledgeable of various policing institutions, the Clown Prince of Crime must've been a war veteran of sorts, who worked for some kind of agency or shadow group and either hated it, or was driven insane by the horrors of war.
hokky used viable examples such as Joker knowing the right actions to make during Commissioner Loeb's memorial, the exceptional bank heist at the beginning, escaping the Major Crimes Unit (MCU) and, basically, beating the trinity of Batman, Gordon and Harvey Dent.
It'd be fair to think, "well surely records of the Joker's activity would've been kept on file", but neither Alfred nor Gordon could find anything on the Joker's history.
But How This Links to Blake?
When Blake turned up on Bruce Wayne's doorstep and regaled with him the tale of his young life, he told the Wayne that his father had passed when he was nine years old.
If the Joker was indeed a military man, he could have been released, or disappeared from his job, and returned to his young family a broken man. Racking up a million debts to a million different terrible people, including gamblers, his family could have suffered from said debts, leading to how he got those scars and how John Blake became an orphan.
Perhaps the Joker didn't know Blake survived, or maybe they're both fully aware of each other's existence.
The time stamped image above reveals that the Joker carried out the mob bank heist in 2008. 8 years later in '16, Blake turns up at Wayne's door with his story. Meaning that the Joker possibly turned his life to terrorism during the hiatus from his shadow ops role. And:
This timestamp could place Blake's date of birth down to some time in the late '90s, making him a pretty legit age for a rookie cop in The Dark Knight Rises.
PCVCsquared believes that Blake and Joker share thematic elements, the biggest hint arising from Blake's monologue in Wayne Manor:
Not a lot of people know what it feels like, do they? To be angry...in your bones. I mean, they understand. Foster parents, everybody understands...for a while.
Then they want the angry little kid to do something he knows he can't do: move on.
So after a while they stop understanding. They send the angry kid to a boys' home. I figured it out too late. You gotta learn to hide the anger. Practice smiling in the mirror. It's like putting on a mask.
"Wearing a mask", feeling misunderstood? This all screams a duality containing elements from the Clown and the Bat. PCVCsquared places it quite nicely:
So we've got the Joker saying "Why so serious? Let's put a smile on that face!" and wearing facepaint, and a young John Blake learning to hide the anger in his bones behind a smile.
Both of them are resourceful, smart, look like they could be closely related, and have a seemingly innate understanding of Batman.
Both of them hide behind a smile. Like father like son?
All genius level, masters of theatrics.
What if the Joker wasn't military, and was tortured over debts, whilst his wife died in suspicious circumstances. In the same monologue above, Blake reveals how his mother came to pass:
See, my mom died when I was small. Car accident, I don't really remember it. But a couple of years later my dad was shot over a gambling debt. I remember that just fine.
Was that the straw that broke the Clown's novelty braces?
If this theory turned out to have a shred of truth, then that means the Joker's tale in TDK could've touched upon the sad story of the Joker's creation from the seminal graphic novel The Killing Joke. But in an ironic and beautiful stroke, this could also mean that the spawn of the Joker becomes Gotham City's second watchful protector. And that's pretty cool.
All in all it's a great theory, and a sweet nugget of fun that's creating some awesome fan fiction in my mind. But until Nolan and Goyer step out and say "yes" to it, it'll remain a mere really good idea.
