She was born with this spirit tethered to her, and in limited capacities, she can make Aiden perform specific tasks. Aiden's existence is, for many years, inexplicable to her. She possesses an attachment to an unknown spirit she refers to as Aiden.
Primarily, you're in control of Jodie ( Ellen Page), a woman born with an equally exceptional and unfortunate gift. The Two Souls part of Beyond's title refers to the dual entities you control throughout the game.
And yet your enjoyment of Beyond will once again depend entirely on how willing you are to get behind what a David Cage game unwaveringly is, not to mention how willing you are to forgive some frequently hokey, and downright maddening plot nonsense. In Beyond, Cage has developed a game that shows far greater production value, offers significantly better acting talent, and tells a far more coherent story than anything his studio has tried previously. Cage and his team at Quantic Dream have dedicated themselves to a laserlike focus on melding cinematic storytelling with the interactivity of video games, and Beyond is perhaps the best realized version of those ideals and mechanics. Beyond: Two Souls is a great deal like those two games in terms of mechanics and design ideals.
If you've played either Indigo Prophecy or Heavy Rain, you know precisely what that means. David Cage has gone and made his game again.
