Ep 12. The Spanish Teacher

In Glee season 3 episode 12, titled "The Spanish Teacher," viewers are introduced to a new character at McKinley High School named David Martinez. David is a substitute Spanish teacher hired to fill in for Will Schuester while he is away competing in a national competition with his own glee club group, the Troubletones.

Will is excited to have hired someone with David's credentials, as not only is David a fluent Spanish speaker, but he is also a songwriter and former member of a popular boy band. David's credentials quickly impress the rest of the glee club members, making him a welcome addition to McKinley High.

In an effort to win over the students and establish a rapport with them, David decides to incorporate his musical talents into his lesson plans. He asks the glee club members to perform a Spanish-language song as the opening act for a school assembly. The chosen song, "La Cucaracha," is a classic folk song sung in a humorous and lively manner.

However, not all of the students are eager to participate in David's lessons. Santana, who is fluent in Spanish, feels like David is not teaching them anything they don't already know. Meanwhile, Mercedes thinks that David is not taking the glee club's reputation seriously enough and is worried that by performing a comedic song in front of the school, they will not be taken seriously.

Despite some initial resistance, David's personality and charisma quickly win over the majority of the glee club members. They begin to enjoy his lessons and appreciate his musical talents. Meanwhile, Will begins to feel threatened by David's popularity with the students.

As the episode progresses, David's true intentions are revealed. He has been using his position as a substitute teacher to scout for new talent for his boy band. He offers a spot in the group to one of the glee club members, much to Will's dismay.

Ultimately, the episode ends with a performance of "A Little Less Conversation" by Elvis Presley, featuring the glee club and David. Despite some initial setbacks, the glee club members have grown to appreciate David and his unique teaching style. Will realizes that he does not need to compete with David and instead should focus on his own teaching abilities.

Overall, "The Spanish Teacher" is a fun and entertaining episode of Glee that showcases the talent of the show's cast while also introducing a new and interesting character in David Martinez.
