I would put Courtney Love inside. She could be on remand for well.... being herself.
I would imagine she would take over the drugs trade with Reb, set up a ring of pros on the outside that Chrissie would manage, write really bad music like Sheila Brady who stole Pixie's song from Judy, get lizzie to make a still to keep everyone giggling and constantly be fighting in the laundry with bea!
She would then be sentenced to life and shipped off to Blackmoor to be top dog.
