3) Maggie Murdock
In case you didn’t know, the nun who tends to Matt in a flashback scene during season two of the show is hinted to be Sister Maggie, the woman who turns out to be none other than Matt’s mother in the comics.
Maggie left the Murdocks when Matt was a baby as she suffered from post-natal depression, leading her to try to hurt her child. Her horror at her actions led her to retire to a convent where she remained out of her son’s life, until fan favourite storyline Born Again” brought her back into contact with Matt.
Her arrival would bring some much needed light into Matt’s life, right when he would need it most after losing Elektra. Maggie’s introduction would also hopefully mean that the season would be adapting “Born Again” which, as one of Daredevil’s seminal storylines, the series needs to tackle sooner rather than later.
