In the part right Jabba dies, R2-D2 zaps leia's slave hold chain with an electric current (or something like that).For those of you who didn't know,metal conducts electricity.Well,leia's chain is made out of metal,so I was thinking,if the metal conducts electricity,and the chain that was holding WAS metal,why didn't she even flinch? (that was a big looking current of electricity...)
