Mrs. Carr was a chaperone at the Lock-In, appearing during The Ugly Truth. She suggests the students at the Lock-In play icebreakers to get to know each other better. She suggests that they should start with the "Name Game", in which you create a nickname for yourself to matches your personality. One stipulation of this game was that the name had to employ alliteration.
