Leia's chain was attached to a loop on her collar around her neck and held by Jabba. The chain served as a leash that Jabba used to control Leia and the rest of his slaves. The chain was originally very long until broken by R2-D2. After R2-D2 freed her, half of her chain was still attached to her collar, a reminder of the slavery she had escaped from. Jabba used the chain to prevent Leia's escape and also to control her. By tugging on the chain from time to time and choking her he reminded Leia of his mastery over her. Ironically, she would eventually use the chain to strangle the Hutt Lord to death.
Leia's Perception of her ChainEdit
Leia despised her chain the most out of her whole costume, along with her collar, as it gave Jabba complete control over her by keeping her on a short tether letting Leia go as far away from Jabba on the throne as the chain would allow. Leia hated that she felt the cold chain against her naked back, along with Jabba's constant tugging, and yanking keeping her close as possible to make the scantily clad princess not to stray far from him, especially on the sail barge. If she ever resisted a yank, he would follow up her newfound courage with an even harder yank, forcing her to either run towards him, or force her back against his bloated belly. Leia was replused most when Jabba choked her as she had to gasp for air in pain. She was always annoyed when Jabba played with the chain, reminding her of her place as his slave. Jabba loved seeing the half naked princess in pain from his tuggs and yanks of her chain, Along with her collar, this showed everybody the proud princess was now a pet to the Great Jabba the Hutt. She also hated feeling the cold chain against her naked back when she slept, as it would often move causing her to make her self comfortable adjusting her self accordence to the chain. Also when Jabba yanked her chain for her to sleep on his belly feeling the coldness of it on her cheeks.
