Here’s a quick refresher on where things stand with Mark, Helly, and the gang The second season of Severance, which debuts tonight on Apple TV+, proves that the corporate sci-fi drama has still got it.

Taking the idea of work-life balance to extremes, the sardonic and surrealist thriller “Severance” on Apple TV+ envisions a dystopian corporate world in which employees of a company called Lumon Industries have a chip implanted in their brains that severs their memory in two.

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.

See at Roku Channel. Right now, you can watch all nine episodes of Severance season 1 on the Roku Channel, from the premiere episode (The Good News About Hell) to the season final
