I DO wish we could have seen Kurn later in the last season during the whole dominion war arc. Possibly as a loyal Klingon fighter who ironically ends up loyal to Gowron. That would have been interesting.
That would have been really good! Not even that far fetched, as Kurn once fought for Gowron during the Klingon Civil War. He could have been living as "Rodek," Gowron figures out who he really is and uses it against Worf. Worf is then faced with having to kill him knowing it was his brother.
