A healed Donut returns from Red Command with new pink armor, which he insists is "lightish red". Sarge pokes fun at Donut by addressing him with feminine titles like "Madam","Strawberry Shortcake", "Pretty in Pink", "Barbie", and "Princess Peach". Sarge reveals that Lopez is actually a robot, which Grif has trouble with ("Did the fact he never talks get to you?" "I just thought he was a silent guy." "Not even that he drinks motor oil and sleeps standing up?" "I thought he was just trying to impress me"), and finally gets around to installing his voice card, but neglects to ground himself; static electricity damage to the card results in Lopez's inability to speak anything other than Spanish, which none of the Reds understand.
