4. Irving has visited the testing floor before

Now, a lot of people will cite star-crossed colleagues Burt (Christopher Walken) and Irving (John Turturro) as the most beautiful part of the series – which is why it was so devastating when Burt was forced to retire from Lumon.

Perhaps the key to unravelling their office romance, though, is the fact that ex-military officer Irving keeps painting the dark elevator that leads to Lumon’s testing floor. He paints it over and over and over again. This seems to suggest that he’s been there at least once before, making us wonder how long he’s been at Lumon in the first place. Could he and Burt have met many, many, many times before?

Whatever the reason for their meth lab-intensity levels of chemistry, here’s hoping they find love in a hopeless place all over again. Either as innies or outies (even if Burt has a partner in the real world) or both.

5. The future looks bleak

It’s made him a target of Mr Milchik (Tramell Tillman), but Dylan (Zach Cherry) made the ultimate sacrifice in the finale when he agreed to stay behind and trigger the ‘overtime contingency’, thus allowing all the innies to wake up in the outside world and cause some serious mayhem… until it was abruptly shut down, leaving everyone’s fates uncertain.

Now, though, we can confirm this: the future is bleak. “Things get darker,” series creator Dan Erickson told Vanity Fair. “We very much wanted to put our heroes in a scarier place because season one ends with them poking the bear. They form this little rebellion, and they’re able to achieve a modicum of success with it, but the question with season two was: what happens when the bear pokes back? What’s the fallout of this victory that they had?

“I think, without giving much away, the fallout is dire.”

With that caveat in place, only time will tell how the likes of Alia Shawkat, Stefano Carannante, Bob Balaban, Gwendoline Christie and a suspiciously young Sarah Bock will fit in at the Lumon office. Thankfully, we don’t have long to wait, as the second season of Severance will debut on Apple TV+ on Friday 17 January.

Here’s hoping it answers some of our biggest and most burning questions before too long…
