My theory is that it’s his wife. She seems pretty competitive, and I could see how it would really wound a misogynist narc like Rhys to be bettered by a woman. It would explain the rape allegations and possibly also the trooning out - he’s very fond of the “I’ll show you!” mentality, like when we called him doughy and he posted that photo of him posing like a man. I could really see him deciding to get his own back for years of perceived humiliation by deciding, “I’ll become a champion female athlete! That’ll teach her!”You can tell that Rhys is uncomfortable when he's not the strongest, fastest person in the room.
Does he have a sibling or cousin there was a major rivalry with? It seems pathological. He strenuously avoids rooms where this isn't the case. It's only his safe space when he could fight anyone there and win.
