There might be a big moment coming down the road for the winners of EW’s Best TV Couple of All Time bracket game. And it all will start with Patty Duke and Meredith Baxter. (Warning: Sizable spoilers ahead!)

Glee has enlisted the legendary actresses to appear in the show’s season finale, where they play a lesbian couple who end up becoming mentors for Kurt and Blaine. According to E!, who first reported the news, Blaine (Darren Criss) will meet Duke’s character while shopping for an engagement ring for Kurt (Chris Colfer).

Duke and Baxter’s characters are also set to appear in the fifth season of the musical comedy, which has not yet been officially announced by Fox.

Duke won an Academy Award in 1963 for her role in The Miracle Worker and Baxter is best known for playing Elyse Keaton on Family Ties.
