He merely only deals in fixation, preoccupation, and obsession. I wouldn’t go as far as to say that he is secretly in love with Jules, mainly because I don’t think Nate loves anything or anyone. He’s also confessed to Maddy that he’s going through a lot and is “confused.” But Nate’s also shown a recurring fascination with Jules (and her being trans) both during lengthy text message exchanges using the alias “Tyler” and during some IRL stalking. He’s shown an abnormal discomfort around other men’s penises in the gym locker room, but his phone is filled with pictures of them. This is compounded by the fact that something seems to be up with Nate’s own sexuality.
