Ambrose looked at Buffy. We? Over his dead body. "You Buffy will sit down and try to not make anyone angry." With that he turned to unlocked the door and open it.
He knew the etiquette and knew that harboring another slave was not good for any of them, but there Lucius was and what could he say? She didn't tell us she was here with out permission. Even Lucius was not stupid enough to listen to that.
"I was wondering when you would make another appearance at my home. Apparently we have the same problems in humans." It was a bit cold, but Ambrose had an appearance to up hold, at least until the door was closed. "I would ask you in, but I assume you would push past anyway." He moved to let Lucius in, even though his whole body screamed for the man to leave. Once the man was in he closed the door. The weather was getting worse.
