Subaru wakes up, in the bed, once again, with the twin maids sitting beside him.
This time, he volunteers to work at the mansion once more and spends as much time with them as he can, working his utmost to earn their trust from the start, so they won’t suspect and kill him! His second priority is finding and stopping the shaman who killed him (and most recently, Rem) in previous loops.
For the latter part, Subie learns from Puck that he has the somewhat rare “darkness” alignment, rather than any of the standard four elements. Excited to be able to focus his mana through his “gate” and perform magic for the first time in this world (aside from Return By Death, obv) he gets a little too carried away and blows out all his mana at once.
Like Explosion Girl Megumin in KonoSuba, this exertion leaves him barely able to move, but he’s absolutely committed to continuing his tireless work with Ram and Rem, knowing his life and future may well depend on the results. Everyone notices that Subaru is simply trying way too hard, hiding his churning troubles beneath an overly chipper, caffeinated exterior. Something has to give, and it does, when he’s overcome by nausea.
Emilia is outside the bathroom when he boots, and he can’t fool her any longer, so she takes him up on his desire to lay his head in her lap when the need arises, and it arises. Emilia is so kind and tender and matronly as she gives Subaru something he’s needed for some time: a pressure valve.
Safe in her lap, free of complications, he can let it all out, and Emilia is glad to see him not holding it in. In fact, it proves to her that he’s a truly good person, and she relays that to Rem. It’s such a lovely, calming scene, and the episode perfectly built up all that pressure and tension.
His Emilia-aided lap pillow catharsis, then, turns out to be the means by which he achieves his first objective: earning the trust of the staff. Emilia assures Rem, who tells Ram, who tells Lord Roswaal. I’d like to think that’s how it works, anyway!
That catharsis and its positive effects would not have been possible if Subie had been a mere house guest and not someone doing his part in the mansion with the maids. He’s done being lazy and half-assing things; that’s how people have died in the past.
Of course, there’s still that shaman to contend with. He believes both he and Rem (at different times) were hit by a fatal spell in the village. Now he and both sisters will be going to the village together, and thanks to “Beako”, he knows there’s a way to detect a spell before it’s cast (much like a boss’s big timed attack in RPGs).
But once that spell is cast, it can’t be un-cast, so I hope to hell he’s careful and doesn’t have to go through all of this yet again. Another important thing he learned was that people who help him prefer simple thanks to elaborate apologies.
Honesty and simplicity are Subie’s tools of salvation. Cry when he has to, accept help without shame, and thank those who give it. If these people see every side of him, not just the artificial ideal, they just might not end up being the “poisonous flowers” he dreads.
