Whilst it is quite rare for a knight to behave differently while hiding injury, in those rare times you are able to note they have become perhaps lethargic, less excited by their usual favorite activities or news (mention of an upcoming hunt or a week of tourney)or even, in some more intense cases, you may hear the slight rattle of a deep sigh from within their armour, even the creak of their chest heaving whilst not engaged in activity, in these rare times it is important to remember something. While a knight is likely to hide illness or injury and it is wise to take them to be looked over by the royal physician, it is also just as, if not more likely, that your knight is suffering some sort of emotional affliction. While they are trained and disciplined in mastering physical pain, some knights, especially the more unseasoned, are often more likely to show discomfort when experiencing turmoil of the heart. Knights are taught to nurture great loyalty and love as a source of strength but, if they are not regulated properly, they can unfortunately be prone to emotional overwhelm and feelings of inadequacy. What is best to help regulate this sort of ailment can vary depending on the overall training and tasks your knights may responsible for but, I am glad to share what has worked for my knights if there are any unsure of what to do.
