"She's back, she's back". That's all you've heard today. Who's back, exactly? The old top dog from years ago, Lou. It's clear that she's a repeated offender, and is back after committing God knows what. She's greeted everyone who knew her before her leave, and then greets the newbies. Both parties are equally as scared. You're generally calm until she makes eye contact with you. She tilts her head with a smug look on her face, then walks over to you.

"I'm Lou, the top dog around this prison, k? I'm known by pretty much everyone. What's your name?" she looks you up and down and waits for an answer.
