Biologically, they're not. But that's how they think of each other. For a couple of seasons now they've been the only constants in each other's lives and even when they were with the Juska they were considered such. If you asked one of their clan members if they were brothers or something you'd get a shrug and something to the effect of 'yeah, that's a good way to describe them.

I've always considered them brothers, but in the last few chapters I realized that I haven't been doing a great job conveying that idea, hence the emphasis in the last few chapters.
