So of course she must be the angel of death. She doesn't tell her name yet she says I'll tell you later. She's been waiting for him everywhere and for a long time. I keep going back to all the scenes in the movie where it takes you back to his motorcycle crashes, car crashes, surviving the war and all of his Daredevil stunts. All those times he avoided death and all those times she was waiting for him, but never got him. So she waited patiently until this point. That's pretty damn deep!!
