unfortunately i don't have a picture to back this theory up but its in the Netflix TV show in episode 7 with about 7.3 minutes left you can see Matt fighting stick but if you see closely you see cherry blossoms falling.i guess that hints Nail coming to Netflix soon.
Nail is a 5 female assassin group that works for The Hand but daredevil was The hands leader. Cherry blossom is basically a clever girl and betrays Daredevil.
Sorry it was brief and non-descriptive but i just figured this possible Easter egg.
