He's got cuffs...

Mar nodded in understanding. It was grating how insistent she was about wearing those blasted robes but it was clear that they were, like many things about the Jedi, a security blanket for her. So Mar shrugged. "Very well then, in that case you will have to put this on..." He pulled a pair of handcuffs from his belt and handed them to Serenity. "To look the part of a Jedi captured by a 'skilled bounty hunter.' Don't worry they're trick handcuffs, they'll come off with a sharp tug. You will be my 'prisoner' a bounty I'm taking to one of the hutts here on Nar Shaddaa for the bounty on Jedi." He held out his hand. "I will be needing the lightsaber though... prisoners can't have weapons." He smirked warmly at her.

"This is mostly to keep other hunters off our backs. You're a jedi, and those are always going to stand out in a place like this." Mar said as he put the helmet on his voice became modulated as a result. "So always try to look the part, fit in. And the only way you're doing that while wearing that is by playing the role of prisoner."
