While “Glee” has released virtually no production stills from Tuesday’s “Old Dog, New Tricks” edition of “Glee,” it was very forthcoming in its weekly behind-the-scenes gallery.

Featuring, most notably, a look at Chris Colfer’s Kurt in his Peter Pan garb, the photos tease the season’s penultimate episode and Colfer’s debut as a screenwriter for the long-running FOX musical comedy.

Absent from the backstage photos, Santana and Rachel also have storylines in Tuesday’s new “Glee.”

“In an episode written by series star Chris Colfer, Rachel attempts to salvage her reputation among Broadway gossipers by hiring Santana as her publicist and creating a charity for rescue animals. Meanwhile, Kurt nabs the lead role in a retirement home production of “Peter Pan” in the all-new “Old Dog New Tricks” episode of GLEE airing Tuesday, May 6 (8:00-9:00 PM ET/PT) on FOX,” reads FOX’s synopsis.
