"The Hurt Locker, Part One" is the fourth episode of the sixth season of the American musical television series Glee, and the 112th overall.

The episode was written and directed by series co-creator Ian Brennan, and first aired on January 23, 2015 on Fox in the United States.

The episode takes place as Principal Sue Sylvester organizes an event between New Directions and rival show choir groups Vocal Adrenaline and the Warblers.

Sue then quickly hypnotizes Sam Evans (Chord Overstreet) with keywords to make him feel love towards Rachel, kiss her, then wake up and not remember anything.

Blaine Anderson (Darren Criss) tells Rachel and Kurt Hummel (Chris Colfer) that the Warblers will not go easy on them, but is called away when his new boyfriend Dave Karofsky (Max Adler) discovers a live bear cub in their apartment.

Rachel and Kurt give a pep talk to New Directions members Jane Hayward (Samantha Marie Ware), Roderick (Noah Guthrie), Mason McCarthy (Billy Lewis Jr.) and Madison McCarthy (Laura Dreyfuss) about the invitational, and they all realize that their chances are dim since they do not even have the proper number of members for a true show choir.

Kurt goes on his date and meets Walter (Harry Hamlin), a much older man who has only recently come out as gay and had a former wife and kids, and after much awkwardness they agree to start off as friends.

Returning recurring characters that appear in the episode include Iqbal Theba as both Principal Figgins and his twin sister Abigail Figgins-Gunderson, Max Adler as Dave Karofsky, Max George as Clint, Lauren Potter as Becky Jackson, Samantha Marie Ware as Jane Hayward, Noah Guthrie as Roderick, Billy Lewis Jr. as Mason McCarthy, and Laura Dreyfuss as Madison McCarthy.
