What if the television shows Doctor Who, Desperate Housewives, and Arrow are all part of the same universe? Crazy, you say? Well sure. But let me explain The John Barrowman Theory to you anyway.
After the events in Doctor Who and Torchwood, the enigmatic man who calls himself Captain Jack travels forward in time and discovers Earth is destroyed by an environmental disaster. Rather than work with Torchwood he decides to take matters into his own hands. He travels back in time and assumes the name Patrick Logan to conceal his identity from Torchwood.
As Patrick, he becomes an eco-terrorist to stop the impending doom. To escape his crimes, Patrick fakes his own death in an explosion (an easy feat because he’s immortal) then changes his name to Malcolm Merlyn. In the face of tragedy Malcolm decides to become even more of a badass and trains with Ra’s al Ghul’s assassins. When things take an ugly turn, what does Malcolm do? He fakes his own death again, that’s what.
See? There’s a pattern here — morally ambiguous, vengeful, mortality-challenged. Jack, Patrick, and Malcolm could easily be the same character in the same universe. And that’s the John Barrowman Theory.
Mind = blown.
