Hi , everyone,
I don't know how to "quote" sth , so i'm writing myself
OK , so , I've read a lot of q's about this :
The prophet about The Chosen One and The Passenger , blood red horses and angels from the sky , the two will battle and one will survive.
If you're asking they battled (yeah , before the flood , when syd was trying to stop the red ball thingy and Nadia trying to stop her) but none of them died , you're wrong cuz all in all , though Sloane shot Nadia (cuz obviously he loved Syd WAY more) and she was in coma for months , she died , and only one survived , Sydney
But if you didn't meant that , but sth else, than i'm sorry
And 'bout the S3 - end Lauren and files thing:
The project was Project X-mas. Jack's works to make Syd an agent , like mom , like dad. And they were ex-files , very old ones. But after Syd figured out that she wasn't the one who's managing her own life , but her dad was , also after they were bonded that much it was a disaster to her.
