"Comes" is a legal term that means a person who is summoned or ordered to appear in court or before a legal authority. It's like when your teacher asks you to come to the front of the class, except in a court or legal setting. The person who is a "comes" has to go to court or wherever they are summoned and answer questions or give testimony. It's important to listen to the summons and go where you're told because not doing so can result in penalties or even legal trouble. So, kind of like when your teacher calls your name and asks you to come up to the front, except in a court and the person who is called has to go.
