SEPARATE PATHS. On your homelink: the penultimate fifth-season episodes. WHEEL OF FIRE--"At least now things will settle down," G'Kar (Andreas Katsulas) comments when he returns from the Centauri War. But the clamoring cult of personality surrounding him continues, prompting G'Kar to consider leaving Babylon 5. Plus: Garibaldi (Jerry Doyle) confronts his present problem and future hopes. And Delenn (Mira Furlan) learns she is pregnant. OBJECTS IN MOTION--Spaceships come, spaceships go. Nothing stays the same on bustling B5--except perhaps the friendship of those who turned the dream of a universal freeport into reality. G'Kar is leaving and his companion is fiery telepath Lyta (Patricia Tallman). Garibaldi, meanwhile, departs for Mars with Lise (Denise Gentile) after settling a score with the planet's leaders.
