Usiku didn't look at Tsuki. "Get Giza, now." He said, his voice cracking.
(I like my characters to have an actual reason behind why they do what they do. Like, for instance, Tanya has Asperger's Syndrome, explaining why she will talk and talk and talk, why she's socially awkward, why she's so emotional, etc.)
(Usiku also heavily relies on his younger brother for support after he does something he didn't mean to do. This is why Gia has been able to convince him so easily to hate the Pridelands, and many other things- it's because Usiku relies on him for so much.)
