One thing that bugs me about the rescue plan is how Boushh brings Chewbacca in largely unbound. Yes he has a chain around his neck but his hands and feet are free. Unless the neck chain is some kind of magical Wookiee restraining bolt he should be ripping people’s arms out of their sockets to flee. They knew this in ANH but seemed to forget it in ROTJ. It’s also pretty clear that it’s Chewbacca and not Boushh who takes out Jabba’s guard in the entryway, so why doesn’t the Wookiee snap the diminutive bounty hunter’s neck?

Seems like a dead giveaway that the Boushh exchange was a poorly thought out and executed attempt.
