Subaru:  This was no act of intimidation, but simple shaking from fear. Seeing this, Subaru took a step forward, not allowing any escape as he redoubled his question. "Frederica left the Sanctuary. She believed you’d open the Sanctuary someday, so she left to make a place in the outside world for the people here. So what have you been doing on the inside?”

Garfiel:  Garfiel had rejected the warmth of the hand his sister had offered him, continuing to cower within the Sanctuary instead.

Subaru:  Feelings of guilt sprung up for digging into the scars on another person’s chest. Subaru forced down the feeling, pressing Garfiel for the truth, his fingers digging into the wounds, drawing blood in the process. “Was it that your mother abandoned you, so you hated your mother, so you hated the world that had stolen your mother from you, so you stayed shut inside the Sanctuary? Here, because you didn’t want to get hurt!”

Garfiel:  “That ain’t…! What do you know…? Don’t flap yer damn lips like ya understand!”

Subaru:  “That’s right! All I’m saying is my own arbitrary guess, flapping my lips like I know what I’m talking about. Only you know what you really think. I’m not your family, so I’m not gonna know unless you come out and say it!” When Garfiel retorted on reflex, Subaru harshly scolded him, pummeling him with words. “If you don’t say it, we won’t know! If it’s not in words, no one’ll get it!”

Garfiel:  “—!”

Subaru:  “If you hate your mother for abandoning you, go outside and get revenge or whatever right this minute! Don’t pin this on us people on the inside! That’s what it is, isn’t it? You’re just lashing out? !” Garfiel’s expression contorted. He went down the stone steps, as if trying to put distance between them. There was no escape. Grasping Garfiel’s arm, Subaru brought his face close enough to take a bite out of him. At breathing distance, he glared into that sad, blood-smeared face and asked. And kept asking. “You hate your family. If you didn’t, you wouldn’t be…”

Garfiel:  “No!! Me…I…!”

Subaru:  In Ryuzu’s words, the truth about Shima, Echidna’s advice, Roswaal’s and Frederica’s behavior, the soft gaze Ram sent Garfiel’s way—there, Subaru had found a different answer. There was a basis for Garfiel’s actions. This basis was hatred toward his mother and fear of the outside world. He raised that conclusion aloft. He raised it, so that Garfiel’s objection might strike it down. Even that very moment, he was not killing Subaru or Emilia but trying to destroy the tomb in order to prevent the liberation of the Sanctuary. He wanted to keep Emilia from taking the Trial, because his fear of the Sanctuary being liberated was exceeded by his inability to watch Emilia being tormented by her past.
