Cassie Tyler, Bad Girls
Cassie Tyler (Kellie Bright). Introduced in Season 4, Cassie was an inmate at Larkhall sentenced to three years for fraud. She was confident, always positive and totally at ease with her sexuality. At the time of her arrival, Cassie was having an affair with her former PA and co-defendant, Roisin Connor. Cassie did love Roisin, but was determined not to show it and was unwilling to settle down. In her heart, she was convinced that Roisin cared more for her husband and children on the outside than she could ever care for her.
Roisin eventually managed to accept her relationship with Cassie more openly. They were last seen heroically rescuing the prison Governor, Neil, from a fire in the library. When she left the show at the end of Season 4 it was implied that she was living on the outside with Roisin and her children, after they both received a free pardon for their heroic actions during the Larkhall bomb.
