This is a case of another character from Daredevil's comic world teased very briefly. When Luke Cage goes to Jessica to ask her to find Antoine she refuses and suggests another private investigator by the name of Angela Del Toro. In the comics, Del Toro becomes superhero White Tiger, a supporting character to Daredevil and one with a link to Iron Fist too, as the amulet she wears to give her powers comes from K'un-Lun, the mystical hero's home city, which was referenced several times in Daredevil.
