Otto:  As he did so, the sadness in her big eyes spread even further. In an effort to chide Petra, Otto, standing right beside her, tossed his voice her way. “Petra. Mr. Natsuki still has something he needs to do. Until he accomplishes it, Mr. Natsuki will not falter. You understand this well, yes?”

Petra:  “But…Subaru’s weak!! It’s dangerous! You should stay with him, Mr. Otto!”

Otto:  “The way you said that doesn’t make it sound as if you have much faith in my strength, though!” Otto’s voice made Petra shake her head.

Petra:  There were tears welling in her eyes as she looked up at Subaru.
human
Subaru:  Subaru got onto his knees so he was on her eye level and then gently stroked her head. “Sorry, Petra. I’m getting you, Rem, and Frederica out of this mansion safe and sound. But it’s not just you three. There’s one more person I have to bring out of here.”

Petra:  “Y-you mean Lady Beatrice…?”
human
Subaru:  “…Even though she hates trouble and acts all lonely, she’s a total busybody, always trying to do everything by herself, suffering ’cause of the dumb answers she comes up with and cowering ’cause she won’t settle things herself.”

Petra:  When Subaru described the girl, the loneliness of her existence made Petra widen her eyes.

Subaru:  “I mean, Beatrice is pretty much the same age you are, Petra. Your heights might be a little different… Come to think of it, Petra, you might be a lot like her first friend.”
gpt
Petra:  “First…friend…?”
human
Subaru:  “After I come back with Beatrice, you’ll probably become friends with her. I’m sure you’ll like her, Petra. She’s awesomely fun to tease.”
gpt
Petra:  “M-more than Mr. Otto?”
human
Subaru:  “Yeah. Fun enough that you won’t have use for Otto anymore.”
gpt
Otto:  Judging from Otto’s expression, he wanted to say something, but Subaru deliberately ignored him.
human
Subaru:  Then Subaru stopped stroking Petra’s head and rose to his feet. “I’ll go look for Beatrice. I plan to try hard enough that I don’t burn to death, but if I do, carve on my tombstone that I died because of the fire from Otto’s oil, okay?”
gpt
Otto:  “Inscribing tombstones being too much trouble, I will give you a smacking if you do not return safe and sound. Truly, I will.” Otto seemed to wince as he made his declaration. Then he tilted his back, turning Rem’s sleeping face Subaru’s way. The princess, still asleep as always, couldn’t even bear witness to Subaru’s resolve as he prepared to depart. That was fine. It wasn’t Rem’s place to see Subaru off. It was Subaru’s job to go to her.

Petra:  “—Subaru! Be careful, okay? !” Petra offered up her very own repel crystal. Accepting this, Subaru set off. He did not reply to Petra’s voice as she called out behind him. Petra didn’t need him to do so, either.
