"Glee" is giving fans a "Wonder'ful" treat: Katey Sagal as Artie's mom, Nancy Abrams.
In a behind-the-scenes video, Sagal talks about her role on "Glee" and fans get a sneak peek at a scene between Sagal and her TV son Kevin McHale.
"She was everything and more I could've hoped for to work with," McHale says below. "It was insane."
Take a look at the video and new photos from "Wonder'ful" and the "Glee" Season 4 finale, titled "All or Nothing."
"Glee" will not only return to Fox for a fifth season, but the network has also ordered Season 6 as well.
"Glee" airs Thursdays, 9 p.m. ET on Fox.
