Mabel Thomas (Mabel King) is Raj's and Dee's divorced mother. She is typically the voice of wisdom and authority, and a parental figure for Dwayne and Rerun, who approach her for advice as well. Mabel's ex-husband drifts in and out of her life during the first season. Her role became less important in later episodes and eventually she disappeared from the show altogether, although her character was never written out and was still referred to. Her trademark phrase is "This is true," when agreeing with a statement someone made. Reportedly, King left the show due to a disagreement over the direction the series was going.
