I saw the before the bedroom scene. Suzan was alone on the couch. Her body English suggested she was upset. Hector went into the kitchen which seemed to agitate Suzan. She started yelling at him. He didn't reply much. She stood up on the couch and screamed at him and started throwing things. He came over and started picking up some of the things. Eventually they were nose to nose yelling until she slapped him a couple times. He pushed her down onto the couch and walked away. She threw the clothes rack on the floor and went into the bedroom.
She was mad at him for something and what I saw she was the one that got that fight started.
I don't think the other guy is the issue. Hector and him were fine after the fight. They hung out together and he helped bandage Hector's hand.
