Mafia 54. This is where caravans are robbed!

Let's go back to our notes. We have a note from the commander (let's assume it's accurate), which tells us the results of the Emperor's checks on the 2nd and 3rd nights:

Spear and Ment are different, but Spear and Gur are similar. The latter is quite suspicious.
Your commander

Ment's status is "sharp, disobedient." Therefore, Spear's status is "round, obedient," meaning he is a loyalist. Gur's status is either "sharp, obedient" or "round, disobedient," meaning he is either the third, second, or a member of the Mafia, excluding the king. 3/4, the risk is quite high.
Now, based on Spear's status, let's look at the notes from the second night:

Gur is an elf spy. It would be good to check his obedience.
Kind and handsome mage

Vishmaster is obedient.
Your servant, who faithfully serves his Emperor.

Spear has something in common with Cheburashka.
Soldier #2

Spear is disobedient, and also smokes, drinks, and bullies children.

Here, I made another assumption: that the real investigator always signs with the same signature, which is rational and logical. That is, the second and third notes are accurate, which means all subsequent notes with that signature are also accurate. Let's move on, the third night:

Ple-Sen has different ears from ordinary people.
Soldier #2

The fourth night:

Ple-Sen is obedient and happy about it
Settler

The signature is different, so we can assume that this note is meant to mislead, and Ple-Sen's real status is "sharp, disobedient." Only one role remains for him - the king. If I made any mistakes, please correct me, because I might have.

Now I understand why the commander killed Ment - they and the Emperor decided to give us INFORMATION in a beautiful and unconventional way by comparing him with two people in the first nights.

The only thing I don't understand is why Carnicero didn't write a note about the ears tonight. He could have simply overslept, or he could have robbed the Caravan on the second night (the Caravan's ND, used by him on the third night, would not be reflected), but why didn't he write about it in the note?
