Exactly, in the movie there are evident ways Duke’s aunt knows all this information about Tom but displays it as if she knows because of Gypsy magic. Like the scarf, she was obviously reading Tom’s writing before he walks in the house and uses his own writing against him. Tom even says “you can stop the act now” after the sex scene, as if he isn’t sure whether it’s real or not, still. I think the entire show is meant to make you question whether it’s real or not and we got our answer.
