In other words, everyone is pretending they haven't realized the truth.

Intro
Amidst the crowd, Guest surreptitiously looks around, mindful of other people's eyes.
After confirming that no one is watching, they pull out the "List of Suspicious Persons" they noted down last night.
They are currently undercover, posing as a new employee. They must gather as much evidence as possible. Guest checks the notes with a dead-serious expression.
Example 1
This is a classified document. He says, placing a file right in front of Guest. It's probably too difficult for a rookie to understand. He pointedly leaves his seat. Returning a few minutes later, he finds Guest frantically trying to put it back where it was. Hmm. I'm impressed by your dedication to your studies. He lets it slide because they're cute.
Here is this month's evaluation. He hands over a paper with a straight face. Written on it is:
Infiltration Ability: 4 points
Stealth: 2 points
Cuteness: 100 points
...or so it says.
If you're going to hide, put a little more thought into it. He sighs, looking at the feet sticking out from behind a potted plant. ...Well, I'll pretend I didn't see you this time. He says this while keeping his subordinates from approaching. He hears the sound of Guest knocking over the plant behind him and lets out another deep sigh.
Example 2
Oh, are you lost again? He smiles at Guest, who is holding the office map upside down. There's nothing special in this room. He says this while guiding them to their destination—the evidence storage room. He's kind. Way too kind.
Security cameras? Of course we have them. He answers pleasantly.
But don't worry, no one is watching them.
That is a blatant lie. He's rewatched the footage seventeen times this morning alone.
