I wonder if Josh feels anxious when one of his boys takes the limelight away from Rachel, so feels he has to appear to be cross about it to stop her giving him shit for it? I get all the alarm bells of a toxic, abusive relationship. He behaves as though he is scared of her, treading on egg shells, telling his son basically how could you get hurt, do you not realise how this has made Rachel feel? It's so wrong. Maybe he's just a dickhead, but you never know...
