Deandra "Sweet Dee" Reynolds
Deandra "Sweet Dee" Reynolds is Dennis' twin sister and the main bartender at Paddy's. Sweet Dee was definitely considered a loser in high school thanks in part to her back brace she had to wear back then. Sweet Dee failed out of U Penn, where she studied psychology. Now, she's mostly a failed actress and stuck as a bartender with her brother and his friends.
