When Beatrice grants Subaru access to her library and starts to heal him, he panics, just as I would if I realized I’d just overwritten a saved game at a crucial point. Considering all the crap things that happened in this loop, Subaru can’t let this point of time become a save point.
Beyond stopping Subaru from stabbing himself with a broken piece of her tea set, Beatrice either can’t or won’t help much, aside from telling Subaru that everything she’s said and done has been in accordance with the “Gospel” and for the sake of “mother”—presumably Satella, the Witch of Envy, but who knows?
While I’m skeptical Beako doesn’t care at all about Subie or anyone else, the two are unable to make any further progress as Elsa enters and disembowels Subie. He’s clearly hugely relieved to Return by Death back in the ruin, shaking off the last attempt and comforting Emilia.
Emilia’s beautiful dreamy piano leitmotif plays, as if to indicate the mood has re-lightened and there’s optimism in the atmosphere. Otto, who is unaware this is now Subie’s third time, finds his calm both concerning and comforting.
Before Subaru can meet with Roswaal (again) and this time try to get more about Beatrice out of him, he is brought to a quiet field by Garfiel so Ryuzu can speak to him. It’s productive in that he learns that because Frederica is Garfiel’s half-sister and was born to a human mother, she can pass back and forth through the sanctuary at will.
Meanwhile, Subaru is determined to find a way to liberate the Sanctuary without Emilia having to go through the trial. He considers it nothing more than his own selfish wish; Emilia may have to face her past one day, but it doesn’t have to be here and now.
To that end,Subie announces to Ryuzu and Garfiel his intention to undergo the trial in Emilia’s stead. Once he says this, Ryuzu has Garfiel restrain him and then knock him out. When he comes to, he’s tied up and gagged in a stone cell. Why, do you ask? Because as soon as he came out of the ruins he reeked of miasma—what he calls the “witch’s scent”—which means Ryuzu and Garfiel can’t trust him.
This is an interesting complication. The miasma could be an innocent by-product of Subaru’s respawning process to which Ryuzu and Garfiel are simply overreacting. But either we nor Subie himself can rule out the possibility he is an unwitting cog in a much more elaborate machine: doing things for the Witch while under the impression he’s doing them just for himself or others.
Could his will already be written, as Beatrice claims hers to be? Whatever the case, Ryuzu and Garfiel keep him under lock and key and he wallows in darkness and damp for three days. Garfiel, thinking Otto as a merchant first and foremost, dangles a valuable-looking glowing stone at him as payment in exchange for his silence (Otto was the last to see Subie with Garfiel).
Garfiel’s flaw in keeping Subaru restrained, as well as Subaru’s deliverance, lies in the many meaningful relationships great and small he’s built with others. In this case, he is served by Otto choosing his friendship with Subie over a trinket he’s not even sure Gar will give to him.
Otto reports what’s happened since Subie was captured: after a fruitless search for him, Roswaal instructs Emilia to keep attempting the trial, which she’s done the last two days without success. He then details how he’s been in hiding collecting information ever since Gar attempted to make a deal with him.
At first Subaru doesn’t realize why Otto rescued him—and even mishears the word “friend” as “Eugene”! For all the people stonewalling him and making his internal organs external, he still has friends like Otto to help him in his time of need. While not as deep or profound as Emilia or Rem, his bond with Otto, and the things they’ve gone through, are still significant.
It’s a good thing too, because were it not for Otto Subaru would still be rotting in that cell for as long as Ryuzu and Gar want him there—say, until the barrier falls (if that can even happen without Subie). Otto leads Subie out of the dungeon and to a “very reliable helper” he’s lined up: Ram, who is just wonderfully smug and cool as she declares even if she had to wait for them so long she’d become a old granny, she’d be a cute old granny. Damn straight!
This episode ends with Subaru on an encouraging upswing, with ample time to reach the mansion and armed with a bit more intel. But many concerning looming questions remain. How exactly will he be able to keep everyone in the mansion from an Elsa-slashing? What exactly is Beako’s deal? Are all of Subie’s actions following a sinister predetermined path without him even knowing it? Is he just another Witch’s tool, kept in line by the mere illusion of free will?
