if you didn't know in b43 there will be an NPC update that allows you to talk to and interact with NPCS that are essentially randomly generated, My idea is to be able to either befriend your prisoner by giving them nice stuff like playing cards, chips and other things, you could also use your prisoner as bait for the zombies to distract them while you make a run for it. Of course, you can't exactly expect the prisoner to not run away while not being tied or anything, so, handcuffs, can be found in police stations or prisons while zip ties can be found in housing or grocery stores, zip ties however would be easier to break out of than handcuffs, additionally there would be a chance that instead of your prisoner running away he stays to ambush you and take your stuff or maybe, he'll even plan to take revenge on you and kill your character or whoever imprisoned it, it would be fun for your character to also be able to be imprisoned by someone and try to escape, as I don't think itd really fit PZ for only your character to be able to imprison people
