If her facial features were at least similar, I could buy the excuse that Morrigan was redesigned with the basis of accepting parts of herself... but that doesn't explain at all the complete alteration of her face that makes it so there is no similarity in facial structure. If not for the relative clothing style and the lovely voice actress, the only way we'd know who it was is by the story itself. A better excuse would ha🌜ve been, she was taking over someone else's body... but then we wouldn't have had Claudia Black's voice either.
