"In Series 4, Nikki and Helen have left and you have a new lesbian couple in Cassie & Roisin. They have been imprisoned together and must work at keeping their relationship intact while. Their storyline ran through S4."
"Great show revolving about Spencer and her love story with best friend Ashley. Having a well made teen show centered around a lesbian and a bisexual girl is something unusual. It ran for three seasons."
"QAF is a great show and in episode 1 you meet Melanie & Lindsay, a lesbian couple who have just had their first child. They are only secondary main characters who take a backseat to the guys, but they get their share of screentime and an abundance of storylines dealing with children, marriage and fidelity issues."
"This is the original QAF version from the UK, and has Romey & Lisa as the lesbian couple who have just had a baby. They don't get enough screentime, but what they do get is worth watching. Their storyline only runs through S1. Pointless watching S2 for them as only Romy gets a cameo."
"Without A Trace as a show didn't have any main lesbian/bi characters. But it did have a very good lesbian love story in an episode from S4 called "Check Your Head". You can get the S4 boxset or rent the single episode from Amazon in the US."
