A girl living on Deep Space 9 whom Jake Sisko takes on a double date with Nog in the episode Life Support, an evening that Nog's Ferengi manners ruin.
Leanne is a young resident of Deep Space 9 in the third-season episode Life Support. She has recently parted from her boyfriend, and when she asks Jake Sisko to dinner he persuades Nog to come along as partner for her friend Riska.
The evening at Quark's goes badly. Nog behaves as a Ferengi male is taught to, ordering the girls to be quiet and telling Riska to cut up his food for him, and the two walk out in disgust.
Jake is furious, and the quarrel briefly threatens his friendship with Nog until Benjamin Sisko reminds him how different their upbringings are. The boys patch things up by getting themselves locked in a holding cell together.
