this is a really interesting concept to consider. i think that philip would have had very traditional views on what kind of woman caleb should be with even regardless of the whole witch thing, so i don't think he'd like her more wild and carefree personality (he would definitely compare her a lot to other women of the time period). i also think that even outside of how she is as a person, regardless of anything about her, philip would grow to dislike anyone for "taking caleb away from him" even if they were the nicest person ever. i just can't imagine a world where he'd ever accept that happening, even if caleb's partner was a human who met all of the stereotypical standards for a woman of the time period. philip would always find a way to dislike anyone who gets too close to caleb. clingy younger sibling things.
