- Adaptation Displacement: There's a stage musical version. Seriously.
- Ensemble Darkhorse: Jim Fenner.
- Foe Yay: Between Fenner and Grayling.
- Jerkass Woobie: Sylvia. Probably the least sympathetic of the guards to begin with, but she gets a few TearJerkers. Her first husband commits suicide due to financial pressure and her second tries to murder her for money.
- Many of the jerkass characters have Woobie moments at some time in the series; Denny Blood, Shell Dockley, Buki Lester, Maxi Purvis, Snowball Merriman, Di Barker and Al Mackenzie being the most obvious examples.
- Les Yay: And plenty of it.
- Magnificent Bastard: Fenner. When he's not having sex with prisoners, he's pimping them out or killing off anyone who's a threat to him.
- Nightmare Fuel: When Yvonne gets trapped in the hanging cell and left to die.
- The Woobie: Rachel Hicks, Monica and her son Spencer, Zandra Plackett and Lorna Rose in her last episode
