Who is Empress Ballerina from Welcome to the Monkey House and what is their importance?

The future Empress, at first just a dancer on the television show George and Hazel are watching, takes over for the news announcer when his speech impediment keeps him from completing his special news bulletin about Harrison. She wears very big physical handicap bags and a particularly ugly mask. When she reads the announcement, she disguises her voice to hide its beauty. When Harrison calls for an Empress, she is the first ballerina to stand and face him. When he takes off her handicaps and masks, her beauty is revealed, and she dances with him until she is shot by Diana Moon Glampers.
