S02E09 — Take a Robot to Lunch

The Voltron Force meet Mary Ann, who Coran said was the greatest robotics scientist in the universe. Zarkon's forces have taken one of her robots and turned it into a weapon for evil. Mary Ann, who is a pacifist, gets into an argument with the team over whether or not violence is ever the answer. As she heads for her home planet, Caspia, Keith and the others fear she may be walking into trouble, and decide to follow her. Their suspicions turn out to be right as Haggar and Cossack are waiting. Pidge finds Mary Ann first and provides her with cover fire so she can get away. Haggar then captures Pidge and wants to exchange him for Mary Ann and her robotics knowledge.
