Besides signing up for this, Brandon I assume is getting paid. Hey, you don't follow the rules of the contract (being filmed, yanking equipment off) you shouldn't get paid! Why would Taylor consider staying with him if he is acting like this now. It will only get worse.
Plus, her social media and friends are way more important to her than Brandon anyway. There is no way that is not going to be a continuing argument.
Katie wants Derek to be just like her "bad boy" ex. She's definitely constantly comparing them.
