This or the 4th floor manager (if he is indeed the fourth floor manager) might have killed the rest of the floor managers like he did the second floor manager. If it keeps being men who Charlotte was involved with I could definitely see that being a possibility as well.
Not sure if this would be a spoiler, but just in case I end being right. I think Dietrich is possessed by the third floor manager hence why he is uncomfortable with the 4th floor and I think he might be possessed because he has reached a certain level of corruption already maybe like a condition to be possessed by the 3rd floor manager, this might be a stretch but who knows. I just love how this story has me guessing or theorizing, hardly find stories that make me do this nowadays.
