Something else than sitting around in Ewok village, twiddling her thumbs? Yes, please.
Like destroying the shield generator? Oh wait, that is what she is doing already…
When I said “something else” I was referring to her romance subplot.
She definitely plays a role in terms of the plot both in that and in the rescue of Han but she doesn’t have much internal stuff going on and that’s the main problem with her in ROTJ. Nor does Han for that matter.
