Maybe. . . maybe it is "our" Elizabeth and she's trying to do for this Booker what she could never do for her actual father. . . save him from death. Which makes me wonder if Booker is destined to die in every reality he exists in but in a different way and by saving this Booker, if one would disrupt space-time considerably.
