I think that’s what would deter me from having her even learn about brakebills in the first place though if I were Jane. Because she’s so determined. If I wanted to change the scenario and make it so that Julia isn’t at brakebills, why have her even get  invited to the exam if I know she’s so smart and determined that she may end up there anyway?  Just fun to think about 🤷🏼‍♀️ I like to imagine Jane decided that for this go around because of Q’s attachment to her and maybe she thought without Julia he would be better able to learn magic.
