Carlson had known The Black's scent as soon as he walked in. Another alpha? In his territory? And no warning that he was in the area? Thats almost never good. Carlson took a moment to compose himself. He never likes being mean to other alphas. He lived by the mantra "Do no harm but take no shit" accompanied by an equally important mantra of "Be nice until they are mean". He walked in after The Black, and looked at Kalib. He tried to convey that he should not be intimidated by The Black, and convey it he did. There was no fear, apprehension, or caution on his features. His face was calm, mostly, but a bit like stone. Hard to read
"Most alphas call ahead before entering another's territory" Carlson voiced, shutting the door behind him. "I hope that what you are doing in my territory is important, sir" Carlson's voice had no bite to it. He wasn't trying to be threatening.
