Prior to the events of the series, Matt Murdock accidentally runs into Wilson Fisk. Maybe Fisk's SUV was about to run someone over, so Matt had to throw himself in harm's way to save them while pretending it was an accident, and in the process his cane gets run over. So Wilson magnanimously offers him a ride to where ever he was headed.

On the way, they chat a bit and Matt reveals his background and his desire to make Hell's Kitchen a better place to live, which of course makes Fisk attracted to the young, idealistic lawyer, all the while Wesley is glaring disapprovingly on the side.

Can be canon-compliant or Kingpin can become obsessed with Matt instead of Vanessa.
