Chalk that number up to three times. In the 7 minute trailer (Gameplay Trailer I believe) it shows the Female Exo Hunter commenting on how the player made it this far without dying. Seeing that she is portrayed to be following your guardian, I get the feeling that she knows more about the darkness than the Speaker currently does. It would make sense being that he must remain in the tower and doesn't go into the world but she may also be his helper. On a sidetrack linked to how she may know more, there's a part where Awoken have been shown in an alliance with the Fallen to an extent. That relays to the idea that this lone wolf Huntress knows something more and something very dangerous when she leaves your guardian with a comment about "don't let them get you too." I don't know an exact, decent guess but I'm willing to bet she knows something darker about the enemy or something more about what we were resurrected to do.
