While Will is euphoric over his new job coaching Vocal Adrenaline and all the perks that come with it, he still confesses to missing the camaraderie of New Directions. After learning of a mean-spirited prank his students pulled on rival coaches Rachel and Blaine, he tries to teach his kids about tolerance by making it his weekly lesson plan. A post-op Coach Beiste, who has changed his name to Sheldon, returns to McKinley to receive an uncharacteristically warm but typically over-the-top welcome-back from Sue. While his return has several supporters and a few detractors, it takes a bold move from several old-school gleeks to make him really feel at home again. And the romantic tension that has been brewing between Sam and Rachel finally boils over, while Kurt and Blaine find themselves in a familiar situation that brings back old memories.
