[that gives Shiro pause. He can't... he can't leave Mamoru here. They may have not got along for the longest time, but they were still family. And you can't leave family like that.

He's quiet for a long time, rolling over on his back to look up the ceiling. Soba jumps up on his chest and Shiro strokes his fur]

... I want to go. I do. I want to run away from all thith and never look back. [he shakes his head] But I won't leave you, Mamoru. [he looks over at him] That'd be the dickest move int he univerthe. Leaving you here to deal with everything, jutht becauthe... why. Thome dental work? [he sits up, poking at his teeth] It'th thcary. Terrifying. I don't know what I am, or how much worthe it'll get. [he gives Mamoru a bit of a sidelong grin] You need me. [he just doesn't feel like he can be apart from Mamoru again. He isn't sure what it is, but he feels more connected to his brother now than he ever had]
