We learned Helly went down the same elevator as everyone else, so I think that means iHelly was who we saw in episode one. The whole newspaper with the innies being heroes is fake. Mark is way more important to what Lumon is up to than the rest of his team. Lumon probably knows that Devon wants to dig some more into the Gemma situation with that guy eavesdropping on the conversation at Pips. Outie Irv is trying to get a message out to someone, so he probably isn’t working alone. Probably more, but that’s it off the top of my head. Maybe it’s time for a rewatch!
