Now how about this: we learn that Thrawn is actually the father of Jan's dark jedi twin sister Anne. Kyle's dark twin brother Lyle loves Anne.
Now, don't forget, Thrawn also has a secret twin brother (Brawn). Brawn is basically a granola hippy who lives on Endor, being in 'nature' with the Ewoks. Thrawn is very embarrassed by Brawn's 'slacker' attitude. (Get that haircut, hippy, you'll never amount to anything!)
But Thrawn (being not only scheming, but overly protective) doesn't want Lyle near his daughter Anne. The great plot twist would be that at the end, Thrawn must cooperate with Brawn, Jan and Kyle to fight Ann and Lyle!
Never give in--never, never, never, never, in nothing great or small, large or petty, never give in except to convictions of honour and good sense. Never yield to force; never yield to the apparently overwhelming might of the enemy.
Winston Churchill, 1941.
