If you've yet to meet Letitia in Deus Ex: Human Revolution, then go ahead and watch the above clip. Discussed by Time's Evan Narcisse in this article, Letitia has come across as a racist character to some (including Evan). According to a statement from Square Enix, that was never the intention.
"Deus Ex: Human Revolution is a fictional story which reflects the diversity of the world's future population by featuring characters of various cultural and socioeconomic backgrounds," the statement reads. "While these characters are meant to portray people living in the year 2027, it has never been our intention to represent any particular ethnic group in a negative light."
Whether or not Letitia was created to paint "any particular ethnic group in a negative light," many feel she does.
