Why would a person want a cell mate of someone they don’t like to be anything? (besides annoying or have a good memory (for remembering additional confessions) or something?)

Big: able to overpower

Beautiful: kinda gets to a place of romantic or sexual

Bill: definitely a dude

Edit - there’s a non-zero chance the protestor didn’t have sexual assault in mind, blinded by the pun. We can hope they were pun obsessed.
