Nate in Shining Armor All of the students in the sixth grade are asked to show 5th graders around the school and see if they want to come to P.S. 38 next year. But Nate's "new friend" Leah acts like a person from the medieval times which seems to be a problem. So Nate tries to act like her knight to get her to P.S. 38. Meanwhile, Martin and Ellen come to Teddy's Uncle Predro's help to make a garden for their backyard.
