With its return episode next week, “Glee” begins the march towards the latest McKinley High graduation.

Significant not only insofar as it will end the high school journey for several members of the New Directions, the graduation will also mark the end of focus–at least for now–on the Ohio side of the “Glee” narrative.

But before landing on that momentous occasion, which will occur in the series’ 100th episode, “Glee” must make several pit stops.

Next week’s episode, the first since the show embarked on its winter hiatus, focuses on the emergence of “Frenemies” within the “Glee” universe.

On March 4, “Glee” then presents “Trio.” In support of that episode, FOX shared several promotional photos.
