Did Elektra end up saving him in the end, unable to let that part of her former life go?
The similar comic story featured a Matt that was far less physically broken (although the stress and emotional turmoil was a tad higher), and the comics also didn’t task a brutalized Matt with somehow escaping from a giant underground cavern beneath a skyscraper that has been bombed to smithereens, leaving all of his loved ones to assume he’s dead.
Margaret’s presence is pretty WTF from any angle, but before thinking too deeply about that, one has to try and figure out how in the hell Matt even made it to a nunnery in the first place!
If so, that opens up another box of questions about how she would have even known about his mother, unless Stick was somehow responsible, as Daredevil proper proved that he knew who she was.
