you think their interaction was saved in the ending?
Every characters ending involved Edgar, Celes and Setzer, because they were the only required characters in the WoR. If you didn't notice that, you didn't pay attention much to the ending. When Celes falls and Locke rescues her, Setzer does if you didn't get Locke again. And if Sabin wasn't recruited, then the three of them work together to remove the blockage instead of Sabin by himself. Otherwise, every other ending is identical.
