He takes things into his own hands

As he knew he could just insert a slave retaining bolt to her he then had a cleaver if a little nasty idea. it was a little known fact that Jabba despite being a crime lord was in fact mostly mussel, he could also call back his ancestry to Balori the Hutt one of the few Jedi Hutt's and was one of the few who received training from his holacron.

It was due to this that he could sense Leia overwhelming force potential and found it like an untapped fountain of power very enticing and while he didn't have his ancestor ability to cause force migraines he did excel at force hypnotism.

As he looked into his prey's brown eyes he could feel her trying to resist as she used her limited knowledge of what was taught to her by Luke so far before she had ran off to save Han she felt like she he was playing with her as he began to stroke her mind as if some of the cogs in her mind didn't make sense as she felt a little sick she had to admit perhaps jabba was just misunderstood all these years
