I'm wondering if the writers had this whole Jacen story arc planned since the NJO. What with Traitor
, Vergere, and Terros's Darth Krayt thing. Haven't read the comic yet, but it wouldn't suprise me if Krayt is indeed Jacen, he'd be, what, Cade's second cousin? Not good with family trees.
Personally, I think Jacen is only doing what he's doing for a certain someone.*
It'd kinda suck for there not to be a galaxy for that someone.
We'll see when the next book comes out at the end of the month.
