By now, it was fully clear that their intentions were not innocent or harmless, as family tussles sometimes were, but quite against the nature of brothers; they didn't like each other. Andrezej would likely never love anybody, and the most his, "like," for anyone would go would be mere respect, and everything else would simply be an act put on to secure his own protection. By the time he finally realized that he was as mortal as any of them, it would already be too late for him; for that reason, rather than actually admitting to a well-known fact, he would flaunt his twisted belief until they, too, believed it.
Andre was less surprised that Arkham was his equal even though he had threatened otherwise in many situations; he wasn't an idiot, and knew fully well that any adult could kill him with the swipe of a paw if they so wished. Rather than meekly accepting that which was displayed with clarity, however, and back down, he did not allow such knowledge to stem his provocation; if they came at him, he would not run, but they would not kill him. The Inferni wolves would likely not face a Kaena who returned to the death of one of her last litter dead, and while he did not have any doubt that she would never return, there was the thought.
Anyways, the Inferni would not kill one of their own. It was a law, and would result in a death sentence; that was not to say that he would also hesitate from that. He wasn't much of an Inferni member, himself, entirely alienated not only by himself but by the clan, which likely recognized the danger he could be in the future. No member of Inferni would kill him, however, based on that law.
It was here in his thoughts that his brother rammed him, that he lost his grip on the slippery sand, and fell to his side. He was only momentarily dazed, however, and scrambled sideways across the sand to get back from Arkham for the split second it would take to stumble back to his feet, all the while fiercely growling and holding his muzzle down over his throat protectively.
