Does oMark know who Helena is?
When Mark almost hits Helly in the parking lot, and she reacted with this look, I had assumed this was a normal interaction between two strangers in a parking lot, meant to highlight the fact that the outies didn’t recognize each other. On second thought, wouldn’t Mark recognize Helena Eagan, a member of Lumon’s founding family? Was her reaction of disgust because of her status as an Eagan? Did he realize he almost hit someone important to Lumon?
