Has the requirements to tame Jarrod changed? I'm choosing all the (admittedly old) right answers, and it won't give me the "I'm aghast" option to help tame him at the end

During his meeting, you have to pick "I would advise you against telling women you find the idea of having a wife limiting and a bother" and head to the training room after. If you have the correct version to eventually friendzone him, he will be seen yelling at a servant which awards +5 courage and manipulation (important to end up reforming him in the end!).
To prevent being rivals with him, you will have to reach for a high 450 persuasion but I hope this helps solve your problem!
