After adopting the persona of Lola Glamour and becoming a famous actress, Gertrude adopted a forced stereotypical faux-French accent and began presenting herself as vain and shallow. She mentions that she doesn't have the time for "nobodies" and is dismissive of even the rather expensive trinkets that her richer suitors present to her. However, this appears to be merely a facade based on the way she acts when she recognizes Choo-Choo as her third grade crush. After recognizing Choo-Choo, she acts much more friendly and drops the fake accent in favor of her natural accent.
