Kasidy Yates (Penny Johnson) played a bigger part in DS9 than most Star Trek fans remember. She worked with the Maquis for a while before it got her in serious trouble. Then she shifted her energy back into working with the Bajorans. And she made Ben Sisko (Avery Brooks) believe in love again after the tragic loss of his first wife. It wasnt long before Kasidy and Ben were jumping into a lovely marriage, only for mystical complications to test their union. Marrying the Emissary and losing him to a wormhole wasnt something she expected.
