You didn’t think he’d set things right in one try, did you? That isn’t the Re:Zero’s style. Subaru and his friends will have to suffer and die a lot more until this latest puzzle is solved. Things will get much worse before they get better. Let’s just say I’m glad I have CCS to balance the “ani-negativity”!
Subaru returns to the tomb where he’d just completed the first trial, and finds a shuddering Emilia in over her head. When he later tells everyone he passed the first trial, there are two more, and he can do it in Lia’s stead, nobody, especially Lia, is okay with that plan.
Roswaal, whom everyone there but him serves, wants Emilia to liberate the sanctuary, no doubt as a necessary test that she’s worthy of the throne, but perhaps for other reasons as well. Subaru understands, and meanwhile there’s still the possibility Frederica is up to something.
He decides to head to the manor so he arrives two days earlier than last time, hoping to head Elsa off. Ram grudgingly accompanies him, and is as dry and withering in her disapproval of Barusu as you’d expect when they set off on Patrasche.
Still, Subaru notices something “off” with Ram, and oddly enough, when he made an offhand joke about throwing her as a decoy, she too is surprised how much it bothered her; as if it was something that actually happened.
In truth, it did happen, but in a previous loop. Surely there’s something to her remembering that, if not at all clearly. Speaking of which, Subie decides to tell Ram everything he can about her lost twin sister before they reach the manor.
The two are greeted by Petra, who is too cute for Subie to resist hugging, while Ram is pleased with her manner. Subie gives Ram some time alone with the sleeping Rem and speaks to Frederica, who is pleasant and polite as always, even when Subie starts questioning her.
Frederica claims not to know anything about a teleport trap or conservatives who want to keep the sanctuary barrier up, but as Ram notes (and her and Freddie’s back and forth is great), she could not tell them anything even if she wanted to, due to her oath. Subaru will have to use force to break that oath. For her part, Frederica says she won’t resist.
Their exchange is interrupted by the appearance of Elsa, holding her knife at Petra’s throat. Frederica reveals her beast transformation ability, which proves more effective than Ram’s Al Huma magic. Still, all they manage to do is flee from Elsa briefly, and Subaru is stabbed in the shoulder by a needle-like blade dipped in who-knows-what.
Ram breaks it to Subie that sacrifices will have to be made if some of them are going to survive this. To that end, Frederica uses the blue crystal to fully transform into a stylish blonde lion-like beast (I’m sure she and Kero-chan would get along famously) and leaps back into the manor to stall Elsa.
Despite Ram’s logic, Subaru (and Petra) are determined to save Rem and Beatrice if they can. They’re immediately confronted by a Mabeast, which Ram manages to lure away, leaving just Subaru and Petra. Moments after dressing each others wounds, things get very violent and fuzzy, as we follow events from Subaru’s POV.
When things come back into focus, Subaru is still holding Petra’s hand, but her arm is no longer attached to anything; we then see she’s been crushed by rubble. Subaru runs to Rem’s room, but is once again stopped by Elsa. She talks as though both she and her unnamed client (the Witch’s Cult?) are aware of Return by Death, and that they’d planned for another attempt by Subaru.
Subaru is prepared for Elsa’s killing strike when he’s suddenly thrust through a door, only it doesn’t lead to Rem’s room, but to Beatrice’s library. Beatrice, the one person in that manor with sufficient power to stand against Elsa, even if things didn’t go so smoothly last time she and Subie met.
Only Subie is not happy about being saved. He’s ready to scrap this loop and use Return by Death, not yet willing to accept the sacrifices of Ram, Petra, and Frederica. But as Ram said earlier, he may not have a choice, and is only delaying the inevitable.
