Vivienne is a "neat freak", horrified when there is disorganization or chaos. She has access to all the information and files, which she holds to her advantage, resulting in her. She is rather shy and doesn't talk much, but there is the occasional moment in which Vivienne's louder than an ambulance's siren. She often brings coffee to the Chief, just to butter Bourne up so she can receive a rank higher than an administrative assistant. She has been billed as seductive.


As the administrative assistant of the Bureau, Vivienne requires reports from three different "teammates" (friends who play Criminal Case and are recruited to the player's team) before she can let the player advance to the next case of the World Edition. Besides that, she notifies the player each time they level up in the World Edition.

Also, as of the release of the World Edition, the player may choose Vivienne to join the investigation of each crime scene (in any World Edition case) and provide hint bonuses. She's available as a 3-hint partner. (Note that this feature is only available on the mobile version of the game.)
