 Given Jenna's insecure nature, Liz is generally forced to act as her rock.This has caused Liz some annoyance, especially after Jack increased Jenna's stress level and paranoia by hiring Tracy Jordan and changing the show's name from "The Girlie Show" to "TGS With Tracy Jordan".Liz has been seen complaining about Jenna's erratic tendencies behind her back, usually with Pete.
