Spoilers: For Episode 16 "The Hidden Enemy"
Note: Since this episode was already so heavy on the Vietnam allusions, I decided to take it one step further. Loosely inspired by Tim O'Brien's The Things They Carried.
Jester
On the second day of the battle, Jester loses his weapon.
The fighting is thick and Chopper's just gone down with a leg wound beside him and there's no time, so he grabs the first weapon to hand. It's a fallen droid blaster, and in addition to being poorly shaped, it's dirty. But he makes do because it's all he has, and if he can just push those clankers back again, maybe he can find his own weapon.
But when the battle's over and he's counting their victory in the bodies of his brothers, he still can't find his weapon. In the end he has to take a blaster from one of his fallen brothers, because he can't very well go back to base unarmed. But it isn't the same. It's not a droid blaster, but it's still not clean.
So he takes the weapon back to base, and he spends all night trying to clean it, but he can't get the shine up. It's not his blaster.
Some of his brothers give him almost pitying looks, but he ignores them. He knows that none of them bother to clean their weapons properly.
At 0300 Chopper comes by with another necklace of clanker fingers, and his look isn't pitying. He just nods at Jester and goes on. Chopper understands needful things.
At 0430 Jester throws away the useless cleaning rag, takes up the blaster, sights on the big toe of his left foot, and squeezes the trigger.
He knows it'll only mean a month in medbay. He knows there is no real way out. But at least the medbay is clean.
