The True Prophesy

That's dragging the storyline a bit too far. I don't think that'd be possible now since they've already dealt with all the who's in the prophecy. I think her daughter would have her own story. =)

I think that Sydney is the one in the prophesy because if you remember in season 4 in the finale when her mom said that the chosen one and the passenger will fight and only one would die? and the blood red horse and the angels falling from the sky would be signs of that battle? Well Nadia was the passenger, that was established in season 3. So unless there was another prophesy that was not told, then sydney was really the chosen one
