Well, Ezor's scenes ARE well animated. She doesn't seem to be added later. She moves. Every obviously edited scene has a character stand still and have little to no shading, but Ezor is detailed in at least one of her appearances. I honestly think she was to appear later, after Zethrid thinks she was dead, but in a context that would have made no sense with major storyline scrapped alongside her lines. Or it is just me being hopeful. Perhaps whoever animated her just focused on her specifically and half assed all the other characters.
