How come no love for Cassandra Petersen? She's in huge first episode!

The already-Elvira is billed as 'Dance Hall Girl' in the closing credits. If the episode, her scene is part of the flashbacks to the events of WESTWORLD, but it's not actually from the movie. She gets a couple of nice close ups as she shoots a guy billed as 'Chubby Gunfighter'. I assume she was supposed to be one of the robots gone haywire, although the look on her face in the sequence makes you wonder if she wasn't a human unwittingly shooting another human in all the confusion. Just an interesting bit of trivia, but it would be nice if someone could add her name to the credits for the sake of completeness.
