Nearly three years after one of the most aggressive cliffhangers in recent memory, the mysterious Apple series is about to flip the switch again and finally answer the fates of the core characters.

While “Severance” has a wonderfully creepy-compelling premise, it’s a concept better suited to a movie than a multi-episode TV series.

This story contains spoilers for Season 1 of “Severance,” streaming on Apple TV+. A recap is available upon request. “Severance” returns on Apple TV+ this Friday, but it’s been nearly three years since the first season of the sci-fi workplace thriller ended on a brutal cliffhanger.

Adam Scott, Britt Lower, Zach Cherry, Patricia Arquette and Tramell Tillman all appeared as their 'Severance' characters for the pop-up. Ben Stiller was on hand for pictures.

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).
