Ever since episode 1 of the hit Apple TV Original’s second season landed on one of the world’s best streaming services, fans have suspected that something was amiss with Helly R. Many of us believed that she hadn’t returned to Lumon alongside her fellow ‘innies’ and that Helena Eagan, the daughter of Lumon’s current CEO, had infiltrated the Macrodata Refinement (MDR) team to spy on them for the nefarious biotech corporation. That’s one of seven big theories I proposed following the release of Severance season 2’s first episode.
Well, it turns out I and many others, including Irving B, were right. Irving B has been suspicious of Helly R since MDR discussed what they saw in the outside world in Severance’s season 1 finale. Thanks to a weird dream he has (more on this later), plus the fact that Helena cruelly mocks him during a tense campfire conversation midway through this episode, Irving B determines that Helena is masquerading as Helly R. Confronting her the next day near Woe’s Hollow’s waterfall, he almost drowns Helena in a last-ditch, desperation-filled attempt to force Lumon’s hand and confirm his suspicions.
Long story short: Irving B is right. Helena was planted as a mole within MDR to keep tabs on them and seemingly woo Mark S (the ‘innie’ of Mark Scout), so he gives up on finding Gemma, the wife of his ‘outie’, and uncovering more of Lumon’s sinister working practices.

MacDailyNews Take: There’s tons more in the full article (the Glasgow Block, Dieter Eagan, the Montauk Project, Irving B’s “retirement,” and more) here that explains many elements of “Severance” and, yes, also contains a bunch of spoilers.
WARNING: This video also contains “Severance” SPOILERS!

Note: Woe’s Hollow’s waterfall is not the “tallest waterfall on the planet.” Angel Falls (Salto Angel) in Venezuela is the tallest waterfall on the planet with a height of 979 meters (3,212 ft.)
