Look out, New Directions: Nolan Gerard Funk is coming for a critical member of your singing group.

Michael Ausiello reports that the Canadian actor (Warehouse 13, Broadway's Bye Bye Birdie) will debut on the seventh episode of Season 4 as Hunter, the new head of The Dalton Academy Warblers.

And his top priority will be to lure back the former head of the Warblers in order to help bring a national title to Dalton.

Meanwhile, before Blaine is forced to choose between schools, he may find himself newly single.

On Twitter, Ryan Murphy hyped this Thursday's "The Break-Up" as "the best episode we have ever done” and many fans believe it will mark the end for Kurt and Blaine.
