Not at all, in fact. Get her a purse she wants and she'll reward you with a bit of fun, OR she'll weaponize sex in order to get you to do/buy something for her. She is aromantic, so romantic attachments (or attachments of any kind) aren't something she seeks in another person. She views her "partners" as a means to an end. They are her PROVIDERS. The only form of attachment that Thetis WOULD be able to have with someone is in the form of possession which is powered by the sin of greed. What that NEED for possession or, rather, what ACTIVATES the need to be greedy is if the object of her desire (the person) is desired by someone else who MAY have more success at milking them of their attention. Thetis is possessive of her meal tickets. Even if she finds attachments repulsive, her number one priority IS to be her provider's number one priority!
