McKinley High's Spanish teacher Will Schuester begs Prinicipal Figgins for the job as Glee Club organiser when the former incumbent is sacked.
Will decides to give New Directions some competition between them by having the boys go against the girls, and Terri becomes the school nurse to check on Will.
Will forms an acapella group and spends more time with them than he does with New Directions after he is asked to preform at the PTA meeting with some surprising additions to his group.
Mr Schuester thinks he's scored the upper hand over Sue, but learns hell hath no fury like a woman scorned. Elsewhere, Quinn connects with her funky side.
The New Directions continue to work on their set list for Nationals with a little help from Jessie St James. An unexpected loss rocks the world of one of McKinley's own too.
