Eric Crown knew that Steve Goris was not down with him being his sister's man, he got the vibe since his arrival. He didn't mind, it means he has to prove himself and he was ready for the challenge.
His preference for Jonathan Way was understandable, after all since his sister's disappearance Jonathan was the one taking care of him but he, Eric Crown was not stepping aside for anyone. His sweetheart was his, and he will handle Steve Goris like the brother in law that he is.
Jonathan Way noticed Steve Goris's funny behaviour towards Eric Crown, and immediately went to talk to him.
Both were whispering, and Katie Goris was wondering what they were talking about.
Jonathan just told Steve to mind his manners with Eric Crown, explaining somethings to him about the health care he is receiving and the strong possibility of Eric being his future brother in law.
