Although originally referred to in season 1 episode 6 (Tag Sale You're It) when her son tells Dr. Girlfriend that his mother calls him her "little water baby", we don't get to actually see Rose until season 5. In episode 8 of season 5 (The Devil's Grip) Hank Venture meets Rose while trying to help his godfather and temporary guardian in his lust fueled pursuit of the silver haired beauty. It does not take Hank too long to figure out that Rose is the Quiz Boy's mom thanks to the fact that she sounds almost exactly like her son and bears more than a passing resemblance to Master Billy. While Rose is portrayed as very wholesome, almost to a fault, we soon learn she is very far from naive.
