Ugh. WHY!? For an ironic trip to Tosche Station to pick up some power converters, with a pit stop for a little blue milk along the way? Maybe they'll have to rescue Boba Fett from the sarlacc pit since he's the only man who get can them out of whatever galactic jam they find themselves in? Is Luke going to teach his kids to shoot womp rats in the old T16 in a way that will evoke maximum nostalgia?
Or maybe they just need to pick up the still-smoking skeletons of Aunt Beru and Uncle Jim Nabors (I can't remember his real name). Actually if Han insisted they mount them on the Millenium Falcon it'd be pretty rad.
