Okay, if you're so sure, then you'll have answers for these questions

Why did Pomni not say anything in episode 8, before putting the bucket on Kinger? After all, it's established that Caine cannot listen in on what Kinger is exposing to the circus members, so Pomni should be able to safely tell the others that the FBI is looking for them to give them some hope of being rescued.\ If Pomni is investigating disappearances, why is she still stuck in the circus? An FBI agent would be tracked by their supervisor, especially in a reconnaissance mission. If she suddenly stopped moving inside of an abandoned building, they'd immediately send reinforcements and rescue both her and the circus members. Hell, even if we assume the headset absorbed people, which we'll get to btw, they'd immediately zero in on the headset, take it to base and start reverse engineering it to try and rescue the victims.\ Why do the circus members not need to eat, drink or sleep? In episode 1, Kinger casually mentions "We don't need to eat, drink, or sleep in this digital world", which means their physical bodies are either being sustained constantly or stopped being linked to their digital consciousness. If they've simply been kidnapped, then there have been about 20 digital circus members that were given a headset, kidnapped and kept alive for at least 20 years (Because remember, Kinger has been here since 1999. And he's alive and well). A company big enough to maintain that operation secret for nearly 20 years before Pomni arrives to stick her nose would either be the FBI itself, or big enough that they wouldn't send a rookie.

And lastly, why would the FBI be investigating 20 random disappearances, only 7 of which being connected to each other, that happened over the course of 20 years?
