You spin around and rush through the exit, again.
"Hey! Researcher-person!" the anomalocaris shouts. "Come back so I can check you! Please?" It sounds identical how they said it before.
The corridor walls are blank, again. The ceiling's only feature is repeating light fixtures, again. The only difference is that the passage's color feels greener in tone than it did before. Your chest is pounding and you're putting your all into running. It dawns on you how odd it is for a Foundation site hallway to be like this but it doesn't matter, the junction is just in reach. The light grows more intense and—
"Hi, researcher person!"
You are standing in the containment chamber. The anomalocaris is by your feet, earnestly looking up at you. Again.
You're breathless. "The hell—" Your mind is stabbed by nothing, slicing into any thoughts of speaking you had for several seconds. "The hell was that?"
"I need to do a checkup to make sure no crappy carapaced trilobites are hiding in you."
"But I was… I was just…"
It cocks its head. "Are you dazed?"
"I'm very much fine."
Something is messing with the narrative, and you think you're staring directly at what that 'something' is.
"Do you want to do the checkup now?"
You think you can get past it.
