5) All The Jessica Jones References
Daredevil season two is still a largely standalone affair, but it does feature many references to its sister show Jessica Jones, sowing the seeds of the characters eventually coming together for The Defenders.
Firstly, Claire tells Foggy about treating a guy who is “much stronger” than Matt. This refers to Luke Cage, who she operated on in Jessica Jones’ finale episode. Likewise, Detective Mahoney at one point mentions his colleague Clemons, who was killed in JJ’s first season. The recurring character of DA Samantha Reyes also debuted in that show’s finale.
The finale of Daredevil season 2 features the most on-the-nose JJ reference, as Jeryn Hogarth crosses over to hire Foggy for her law firm. Earlier in the series, Marci namechecks one of Hogarth’s clients, and it’s none other than Jessica Jones.
Along with the Iron Fist reference in season one (the truck holding the chemicals that blinded Matt belonged to Rand Oil – the company of Danny Rand’s father), this means that all the soon-to-be Defenders have been referenced in Daredevil.
