I had a sudden realization about the looping involving Subaru and Emilia. I think we are going to watch a Arc, where Emilia and Subaru are teleported back in time, and have their memories erased, and is going to be the exact same Arc 1 episodes again. With Subaru falling in love with Emilia. With the amnesia, they will have to get new names, Flugel and Satella. Like somebody replaying their favorite videogame with amnesia, and choosing the same exact dialog options. Is not destiny, magic, any type of power or energy. Is just how we are, we do not choose randomly, even when taking options that feel random.
