Yes, but it was on the Lori episode. At that point, it was apt that she didn't know who was behind this. Now, also, she doesn't know who is behind this. So, I think the 0.5 is not related to the current track.
Do you really think they follow the algorithm? But, that being said, I think we need to see which part of the two epics they are crossing.
Also, @Tirch: Do you have The Palace of Illusions? I borrowed it from the library when I read it, I don't own a copy. We need to see the Karn and Arjun angle from the book from Draupadi's pov. Also, the Krishna angle.
I don't have the book with me right now as I am in hometown. By end of the month, I should leave
