it's a leash
in case he runs away i guess

which is kind of funny since he's the one we have actual evidence that he will not run ever
but i guess he could still bite someone. or kill them. like freddie (the leash didn't stop him. but honestly why did urak give him such a breakable segyein guitar like. did he have beef with freddie's family. maybe freddie owed him debts. freddie backstory when)
