There's someone else in the room with K -- it knows this before it turns around, it knows what being watched feels like. It turns only slightly, enough to catch them in its peripheral vision and no more.
It knows who this is, on a practical level. Lock has a habit of referring to his "boss" sometimes, and K has picked up enough about what being Lock's boss entails to come to the reasonable conclusion that whoever they may be, they're not human. It'd resolved to leave well enough alone -- it didn't mind him metaphorically working two jobs, and clearly neither did his boss.
Now, though, there's a little more uncertainty than before. Whoever this is, they don't quite seem like an arcanist either. Something about them feels out-of-place, and-
"Ah, calm down," the other person says, head tilted slightly to the side as they lean back against the desk. "I'm just here to check in on ████, there's really no need to panic."
... ████? Who's ████ -- why can't it remember that name? K's memory is far from eidetic, but that's different from not being able to remember something it knows it was aware of a minute ago. It can feel the blank space where information used to be. It does its best to maintain its composure. Grips the side of its coat with one hand tightly to stop from digging its fingernails into its palm.
"Hm." A small smile flits across the other person's face as they narrow their eyes to look over K again. K recognizes that kind of smile from itself. The hole in the pit of its stomach grows slightly, but it forces that fear down. It's dealt with worse, it tells itself.
"You are really quite interesting," they say, straightening up and walking past K. They put one hand on its shoulder sympathetically. "We should talk sometime, K. Though -- not now. I seem to have caught you off guard."
How the hell do they know its name -- no, there's no need to panic, it's because ████ probably told them, only it can't remember who ████ is. K stares as ████'s boss leaves the room, making damn sure they're gone before it finally drops its shoulders in relief.
Maybe it should've asked... Lock... a couple more questions about his boss. It gets the sinking feeling that might be too little, too late.
