While FOX routinely offers advanced screeners for its original series, it has grown rather protective of “Glee.” The network has provided critics with only one opportunity to review a fifth season “Glee” episode.

That does not, however, mean FOX is committed to perfect secrecy. Over the past few weeks, it has provided extensive photographic looks at upcoming “Glee” episodes.

It has done so again.

The heavily hyped “Glee 100” episode does not air until Tuesday, but FOX has already provided a look at next week’s “New Directions” installment. Featuring appearances from former “Glee” regulars and guest stars, the episode is described as follows:

As the fate of the glee club becomes a reality, April (guest star Kristin Chenoweth) and Holly (guest star Gwyneth Paltrow) plot a plan to save New Directions. Meanwhile, Rachel and Santana attempt to make amends after their blowout fight in the all-new “New Directions” episode of GLEE airing Tuesday, March 25 (8:00-9:00 PM ET/PT) on FOX.
