Apple TV+ put the cast of 'Severance,' including Adan Scott and Patricia Arquette, in a glass box at Grand Central Station to promote Season 2.

The pop-up began when a large glass box appeared in Grand Central's Vanderbilt Hall, containing a replica of the four-seated desk from Lumon's Macrodata Refinement department. Hired actors playing Lumon employees sat at their desks, doing Lumon things (by which I mean, sorting numbers while not having a clue what said numbers mean).

Fortunately, “Severance” returns to Apple TV+ on Friday, and its makers seem to have used every second of the absence productively. The season takes new turns while remaining the most ambitious, batty and all-out pleasurable show on TV, an M.C. Escher maze whose plot convolutions never get in the way of its voice, heart and sense of humor.

After almost three years, the wait for "Severance" Season 2 is finally over. Here’s when the anticipated second season will premiere on AppleTV+ and how to watch it.
