That's the thing about Vicious. Everything always has to be planned, set up as some overly elaborate mind game, when the end result would be the same if they tore this room apart right now. He has to make his point. He probably thinks that he orchestrated everything before and after the coup, down to Spike storming the headquarters.

Some people might call that OCD.

"And what's that?" Spike's voice cuts in once he stands. Oh, he knows what he means, but he'll plead ignorance if it manages to piss the other man off. It's the least he can do for his trouble.
