Subaru:  "As far as I could tell, Rem and Ram are sisters that really get along…" On the way to that room, Subaru told Frederica about facts lost to her: what kind of girl Rem was, what she’d been doing to that point in her life, just how lovely she was. He spoke much like he had to Emilia on the road back to the mansion— "" As Subaru spoke to Frederica, he stated, and replied to, a number of thoughts inside his own head. There had to have been a better way. During the battle, he’d thought I’ve done the best I can. Somewhere, though, there had likely been a better, a more perfect outcome, one with the greatest possible results. And yet, Subaru had let it slip through his fingers. If only he was smarter, surely Subaru would have noticed it. As one example, the letter of goodwill that Crusch’s envoy had brought to Emilia. Subaru had concluded that this letter, the root of much misunderstanding because it was blank, was a plot by the Witch Cult, but in that, he had been mistaken. At that point the Witch Cult surely hadn’t caught on to Subaru’s actions, and no opportunity had presented itself to swap one letter of goodwill for another. In the first place, sleight of hand such as swapping missives wasn’t the Witch Cult’s style; it favored more direct acts of violence, something Subaru knew better than anyone. In that case, there could only be a single truth behind the blank missive. "The contents of the letter of goodwill were written by Rem. I’m the one who asked it to be sent, so if Crusch handed it to the messenger…only the fact that it was handed over stayed the same, and only the contents were erased.”

Subaru:  That was the sloppy adjustment to the erasure of the memory of Rem from the world. If only he’d noticed, if only he’d stopped to think more seriously about why the letter of goodwill was blank, if only he’d seen the truth behind it, he would have realized the tragedy that had befallen Rem. Even if it was a tragedy occurring at a time when there was no turning back.

Frederica:  "That is a rather difficult story to believe.” He arrived at the usual answer to his own question at the same time that Frederica, having finished listening to his story, quietly spoke those words to him. The words held no ring of denial behind them. She looked around the area.

Frederica:  "So this is her…Rem’s room. It is completely tidied up, but…” When the two entered the room—Rem’s bedroom—it looked like a guest room, with all personal possessions removed. It was the same sight Subaru had seen previously, on the go-around when he had returned powerless after the White Whale had stolen Rem from him. That time, too, Rem’s existence had been forgotten. Her bedroom had been just as clean and empty then as it had now become.
