Aaron Stark's vision was of his presumably dead daughter. In "137 Sekunden" it's confirmed that the remains buried at her grave site are indeed hers. They didn't go into detail about how they verified this. I thought they said in a previous episode that her body was mutilated beyond recognition. Did they get DNA results back that fast?
So what could Aaron be seeing in his future? Is he in Heaven like his ex-wife suggests? Or was the DNA test faked to throw him off the track?
