Iron Fist Season 2 packed some pretty major surprises in its season finale even beyond stuff concerning Danny Rand. The episode didn't just give a look at where things are heading in a potential Iron Fist Season 3, but also showed the direction Daredevil Season 3 is headed as well. The latter came via a post-credits scene that rolled right after the Netflix logo and showed Matt Murdock looking bloodied and beaten inside of a church confessional. Take a look!
Matt's back in his black costume he wore before his suit upgrade and sporting some bandages over his eyes that can be seen near the bottom of the mask. Matt is seen holding a rosary and is either talking to himself or addressing someone off camera who can't be seen. Regardless of who he's addressing, his words make it clear this is not the Matt Murdock we've seen in prior seasons of Daredevil:
I once believed that justice could be found in a court of law and in the light of day, but I was fooling myself. Darkness only responds to darkness, and the truth is, I'd rather die as the Devil than live as Matt Murdock.
Yikes, it looks like The Defenders really did a number on Matt. This might be because the building collapse that Matt miraculously escaped killed Elektra, whose fate was unknown following the miniseries' conclusion. Something like that would certainly put Matt in dire straits and possibly rattle his resolve to be so noble when it comes to stopping crime.
There's another possibility to consider, as comic book fans may remember the last scene Matt Murdock appeared in prior to this. The scene found the Daredevil lead in a convent, and was set up to bear a very striking resemblance to an iconic part of the comic storyline "Born Again." The premise of that plot is that Kingpin discovers Daredevil's identity, and goes to work destroying his life in whatever way he can. This might be why Matt is committed to leaving behind his true identity in exchange for his hero self, as returning to life as Matt Murdock could only endanger the people he cares for.
It sounds like a good reason for Daredevil to leave Matt Murdock behind and a solid direction to take Daredevil Season 3, although there are some holes to poke in the theory. For example, it's been established that many in the Marvel Netflix Universe believe Matt is missing at best, but probably dead. With Matt gone, it's hard to believe Fisk would waste time and resources exacting revenge on those connected to Murdock, even if he's a very vindictive man. If Matt is still operating as Daredevil in Hell's Kitchen, however, it probably won't take long for people like Foggy and Karen to realize he's back, which could put the villain back on the trail he was starting to sniff out in Season 2. The people Matt cares for would likely be okay if he just simply disappeared, which probably means Matt has other reasons for keeping up his hero work other than keeping his friends safe.
