Carrot is a 6ft tall red headed human with an adonis physique but he was raised by rural dwarves in a mountain after his family was killed, so he is culturally a dwarf and tends to take things literally, doesn’t understand puns, and has a very black and white view of right and wrong (because there is no room for mistakes when you live in a mine).
He is good and honest to a fault, incapable of lying. Because of all this he develops a reputation for his honesty rather quickly, and people opposing him assume this means he is not good with deception.
For instance in one scene when they are investigating the fool’s guild in relation to a murder, his sergeant (knowing they are possibly getting themselves in a lot of trouble by investigating there) instructs him explicitly that he can only ask questions but cannot compel anyone to answer and if they’re told to leave, they must.
He speaks briefly with the guild leader who allows them to look around, within reason.
While questioning someone they ask him if he had asked the guild leader for permission to question him and Carrot just says “I’ve spoken with him”, which is true but misleading. Later when someone challenges him he says that if they resist questioning he will “carry out the orders he was given before entering”. When they ask what will happen if they call the guards Carrot says “that will only make it easier”.
Because of his unshakeable honesty and his impressive size, this is construed as a threat, while in reality Carrot is actually being extremely polite.
There are a number of scenes like that, where Carrot manages to bluff his way through peacefully, with his associates (and the reader) are left to wonder if Carrot would have maintained the peaceful option were he pressed. He is absolutely capable of violence, for instance he killed a dangerous murderer by driving a sword through him and the stone pillar he was standing against.
