Subaru:  "If it wasn’t for you, I’d be dead and dog food right now. I’m safe and sound because you were there. I’m alive now thanks to you. That’s your doing, not your sister’s." Subaru was simply conveying to Rem his exceptionally simple feelings about the matter.

Rem:  “…Truly, Sister could have done it better.”

Subaru:  “Maybe she could have…but you were the one there for me.” Subaru poured cold water on her weak rebuttal as he brought his left hand over his right, which still held Rem’s hand.

Rem:  “—!” A choked sob escaped Rem’s throat at his words. After that, Rem turned her face aside so that Subaru would not see the look on it.

Subaru:  "I’m glad you were there for me, Rem. Thank you.” Subaru put enough gratitude into his voice to make himself blush.
gpt
Rem:  “I…I have always been a substitute for Sister…”

Subaru:  "Stop defining yourself with lonely words like that, all right? You and Ram are different genres. I mean, she’s the older sister and you’re the younger sister—sometimes you’re gonna clash.”
gpt
Subaru:  "Well, I haven’t really asked why she lost her horn, and since I didn’t ask I don’t know. I don’t know, so I don’t want to talk like I do know, so…” Subaru put his left hand on the upper part of his own forehead—patting it right where Rem’s horn grew out of hers.

Subaru:  "Ram doesn’t have her horn, and you have yours, so you can just do whatever she would need a horn for. You can just be two demons getting along great. There’s nothing stronger than love between beautiful sisters, right?”
gpt
Rem:  “…Ah…”
human
Subaru:  "So I mean, you said you were a substitute, but Ram has no substitute for you, does she? I mean, if you weren’t there for her, can you imagine the state she’d be in?”
gpt
Rem:  “…But…” Yet even so, Rem did not simply nod in agreement. Rem, aghast, didn’t know this, but Subaru had seen such a future. He had seen Ram, despairing at the death of her younger sister, go mad and use all her remaining strength for the sake of vengeance.

Subaru:  "I get it. So, how about we do this? You have an idealized Ram inside you that you can never compare to no matter what you do. Let’s take that ideal Ram you have on a pedestal and send her packing."
gpt
Rem:  “That is…easier said than done. I have always compared myself to—”
human
Subaru:  "That’s why I want you to listen to how I rate her. My rating’s based on reality, not the ideal. Just so you know…I don’t have any talent for reading the mood at all, so I just call ’em like I see ’em, no flattery or mercy.
