"Twins, huh?" Neat, but obviously not the point. The point is that apparently elves don't point swords at each other? The whole thing sounds a little strange to Tony, but he can't really say anything. Pointing swords is probably how demons say hello, so of course he doesn't get it. "That's... strange. So, your Other was really shaking things up by doing that from the sounds of it. He really hated his brother that much?"

Yeah, now he can see why Feivel might be nervous about some of that behavior leaking into his current life. Tony can't think of any reason they might end up on bad terms, but he'd really hate for it to be something completely out of both of their control.
