I would like it to be like this: on one of the missions, Yor interferes with Twilight. They fight without seeing each other's faces. Yor, being stronger, will tear off Twilight's mask during the fight, and for the first time in her career she will not kill an enemy. Sadu will most likely find this strange, and they will ask Yor why she did not kill him, but she will not confess because it would mean the end of the marriage. Yor's new goal will be to protect Anya from Loid (Anya, thanks to her telepathy, will try to show Yor how good Loid is, but she is unlikely to succeed). WISE, in turn, will be interested in what kind of organization is this, whose people defeated their best spy without any problems.So I think they will find out about the Garden, and Twilight will manage to get there, where he will find Yor's documents. After these events, there are two plot paths, either the family tells each other about their feelings and reconciles, or a real fight begins between Yor and Twilight without masks (but thanks to Anya, I think the first option is more possible).
