I might've missed something so there are some scenes that are unclear to me. Could anyone explain what Subaru talking about when he asks Frederica about the "teleportation trap" and what is this "oath" that prevents Frederica from telling them anything? Of course, if the (perceived) lack of explanation is going to be explained later on and is part of the plot, don't spoil it by any means. Thanks.
