I still don't understand how if a man, embroidered in polygamous relationship, that assumes his wives are eloping with each other to get away from him are brainwashed. It is a deep rooted fear, regardless of the type of relationship, in any man that their women might be trying to get away from them. You can't just *assume* that they are brainwashed because they don't have the same mindset as you. Polygamous relationships require an unbelievable amount of trust between all partners involved and can easily collapse if the requirements weren't met. Therefore, unless you or the MC, have the ability to read minds, you can easily think of the worst outcome, depending on the situation you find yourselves in.
