Being a King means he always has a busy schedule.  Prayers are always in order (even if he does not believe in the Gods and he feels they are not his to worship anyway.), political talks, war tactics that must be discussed.  

When he first became King this was very hard for him to grasp.  He never had a schedule before.  Talks were short and to the point, and if not, then they faced Tryndamere’s sword because he was bored and big words made him angry. 

Ashe had to teach him every step of the way.  How to behave, no swords at the table, no backtalk, act kind, if there was a word you did not understand let Ashe intercept.  He hated that at first.  A woman had to teach him how to act but he had grown used to it and now he views Ashe as more than just a woman.  

Sometimes, when there is a few things in his schedule, Ashe allows Tryndamere to roam freely because he needs it to escape the high life.  He is a barbarian with a beast’s blood and he needs to be free.
