Plot 

MDR have a lot of work to do. After glimpsing their 'outies' lives, Mark, Helly and Irving are forced to head back to the office, where Mr Milchick and co are waiting. Under constant surveillance at Lumon, season two will no doubt trace the aftermath of their 'overtime' which resulted in a number of revelations. Let's recap. 

One – Irvin's outie is a retired military man with an adorable dog, a super cool car, and an obsession with tracking down fellow Lumon employees. He also learns that his work crush, Burt G, is in a relationship.

Two – Helly's real name is Helena Eagan, aka the daughter of Lumon CEO James Eagen. To her horror, Helly's 'outie' entered the Severence programme to promote it. In the final moments of season one, she did everything she could to sabotage it, announcing at the company gala that the 'innies' are deeply unhappy on the severed floor. 

Three – Mark gets to meet his sister, Devon, brother-in-law Ricken, and niece, Eleanor. He also realises that his boss, Harmony Cobel, has been masquerading as his neighbour, Mrs. Selvig. After telling Devon that something bad is going on at Lumon, Mark is encouraged to go to the press, before discovering that his outie's late wife, Gemma, is actually Ms. Casey, who is currently trapped on the severed floor.

Season two will explore Mark and Helly's feelings for each other

Speaking about their plans for season two, director Ben Stiller told Variety that the writers will explore Mark's feelings for Helly, as well as Ms. Casey. "We're starting to root for him and Helly, but now we also want to root for Outie Mark to find his wife. That's an interesting juxtaposition and conflict we'll explore in the second season."

The show's creator Dan Erickson, also confirmed to the Thrillist that the mysterious goat room is "part of a bigger thing" that will definitely be explored.
