* AdaptationDisplacement: There's a stage musical version. Seriously.
* EnsembleDarkhorse: Jim Fenner.
* FoeYay: Between Fenner and Grayling.
* JerkassWoobie: Sylvia. Probably the least sympathetic of the guards to begin with, but she gets a few {{TearJerker}}s. 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.
* LesYay: And plenty of it.
* MagnificentBastard: Fenner. When he's not having sex with prisoners, he's pimping them out or killing off anyone who's a threat to him.
* NightmareFuel: [[spoiler: When Yvonne gets trapped in the hanging cell and left to die.]]
* TheWoobie: Rachel Hicks, Monica and her son Spencer, Zandra Plackett and Lorna Rose in her last episode
