Den mother for the Zeta Theta Betas. Loves her girls to death (although she's paid to say they're wonderful), throws a kickass tea party, and grows pot in the back room. Veronica uncovers her sorority secret — much to everyone's dismay. Fortunately, despite losing her painkillers and her job in a campus-wide scandal, her girls are able to raise enough money for another round of chemo. The highs and lows of Karen's life are chronicled in 3.02 "My Big Fat Greek Rush Week" and 3.08 "Lord of the Pi's."
