The ending of the song sounds sadder than it might seem. "there were holes in you | the kind that I could not mend" at first sounds like they were emotional holes, but what if he meant it literally? The brother was hot-headed, "crooked," and it was stated that he didn't know where his brother went. I think the brother did something reckless, and got shot. And he "left that day", as in he died. The brother asks if "everything goes away", which he means "does the pain go away?". Then the last two lines are the protagonist comforting his dying brother, saying that their parting is only temporary, and he'll be there for him, optimistically (imp)lying that his brother wasn't really gonna die.
