Carla is alternatively depicted as both a friend and rival to Erica Goldberg, as well as the on-again-off-again girlfriend of Johnny Atkins. She is a truancy-prone thrillseeker who likes bad boys, shoplifting, and bullying others.
In the season six episode "There Can Be Only One Highlander Club", Carla finds herself attracted to Dave Kim. The two subsequently begin dating. We learn in season eight's "Daddy Daughter Day 2" that they've apparently broken up and Carla is once again involved with Johnny Atkins.
- The character is credited as "Carla Natali" in the early seasons of the series.
