In "Heart," Mr. Schuester challenges New Directions to find and perform the world's greatest love songs on Valentine's Day. Meanwhile, Rachel's two dads, Hiram and LeRoy Berry, pay a visit to McKinley High.
Love takes center stage at McKinley High as Valentine's Day approaches. While Mr. Schuester's weekly assignment to find and perform the world's greatest love songs has some of the Gleeks celebrating romance, for others it serves as a disheartening reminder of what they don't have.
When Rachel's two dads learn of their daughter's engagement to Finn, the seemingly supportive couple offers to throw a celebratory family dinner, but do they have ulterior motives?
Meanwhile, Artie and Rory compete for Sugar's affections, Sam gives Mercedes an ultimatum that forces her to look deep in her heart for answers, a new nonconformist student (played by Samuel Larsen) joins the ranks at McKinley and helps spread a message of acceptance, and Kurt is surprised by the discovery of a secret admirer.
Mercedes (Amber Riley) offers up her take on Whitney Houston's "I Will Always Love You." The performance was recorded before Houston's death, and the release now is a coincidence. The producers have decided to dedicate the episode to Houston's memory with a card in the end credits.
