The episode brilliantly utilizes Janelle James (Principal Ava) here. Usually the source of administrative obstruction, Ava reveals a hidden talent for stepping. The conflict arises when Janine realizes she is out of her depth but struggles to cede control to Ava, who turns the practice into a rigorous, slightly militaristic drill. It is a rare moment where Ava is actually competent and helpful, even if her methods are eccentric.
