Tyal gave Claug a pout and then skulked aside. "Fine, I know." Technically speaking, Arad's wives still had their spots to worry about. Tyal can't do anything before Alice, who knew Arad before her, and neither has any right to go for it before Claug herself. That was the basic form of respect between his wives; each knew her place in the line and would respect the others.
Of course, there were many in line before Claug, and she, too, couldn't do anything at the moment. Of course, all of those rules fly out of the window if Arad moves first.
Claug herself could allow any of the wives to take her spot in the line, for a price, and that price was blood. As a drakaina, she already expected some in-fighting among the wives, and if any can beat her, she'll gladly yield her spot.
