“Rodek’s facial appearance changes slightly between his appearances,” PWE explains. “The Kurn we saw in TNG was often aggressive and reckless. The one we see in DS9 exhibits a more seasoned, if not more pessimistic attitude on life. When Kurn’s identity is changed to Rodek, the individual aspects of his appearance alter in a more subtle way – but together they form a much different looking character. The folds in his forehead are different; he loses the hair on his chin; the shape of his eyebrows change; and most of all, his outward demeanor is not as dark as it was once was – though some may wonder if he remembers anything at all of his painful past.”
Some may wonder indeed.
