Someone compiled some old interviews about Final Fantasy VI. There was going to be another character along with some other good stuff. Check out these quotes and the full interview below.
During the development, for the Tzen event in the World of Ruin, originally if the time ran out, Sabin would actually die! Then if you came back to Tzen with Edgar in your party, it would trigger a scene with Edgar wandering forlornly around Tzen in the middle of the night, searching through the rubble in vain for his brother… “I’m coming to save you!” But we decided that the World of Ruin already had more than enough dark stories, and changed it for the final version of the game. For Sabin fans, it’s a good thing we did!http://shmuplations.com/ff6/During the development, there was another character named Angela, who acted like a stereotypical “big sister” to Cyan. She wielded a whip. She would half-jokingly flirt with Cyan, and he would always brush off and cringe at her attention, but later when he was alone he’d pause and flatter himself to think it was all true. It allowed us to show a shy, private side of his character. There were never any actual romantic connections between the two of them, though: he remains loyal to his departed wife’s memory.
