Seth Milchick is one of Severance's "most important characters" according to the showrunner, but originally he was a bit part until Tramell Tillman showed up
It doesn’t matter to me whether there was ever a mystery because that wasn’t the interesting part. “What are they working on?” doesn’t need to have an amazing answer; it could just be accounting for all I care. What matters is who the characters are, what they have done and will do and why. And more importantly, the way it highlights issues with corporations by drawing interesting parallels within the story. Maybe people in real life will be inclined to question their own conditions and be inspired to protest for better lives.
