The Batman theory: REAL Riddler is Barry Keoghan’s Stanley Merkel hiding in plain sight

Now what seems odd is that Barry is quite the up-and-coming star and this feels like quite a small role for him, but one that surely has a purpose.

Let’s also not forget that he played the creepy psychotic Martin in The Killing of a Sacred Deer opposite The Batman’s Penguin, Colin Farrell.

And considering Barry is playing a role so close to the film’s main detective other than Batman, what if he’s actually The Riddler hiding in plain sight?

Whoever The Riddler really is, he appears to be serial killer taking vengeance by murder, maybe because The Dark Knight refuses to take life.
