Can someone give me an idea on how to complete this conversation?

I am writing a historical novel, a husband and wife (Edmund and Ardellia) go to his acquaintance's home in hopes of a desperately needed business proposition. During an evening when Ardellia and the host meet for the first time. He(the host) behaves very antisocialy. Now I have the scene mapped out but Ardellia needs to complain or rather comment on the man's behaviour. Edmund practically worships him and subtly defends and rationalizes, waving his wife off. Read it, and please give me ideas on how I can write out the rest of it. I'm not looking for critique.and am unwilling to change any of these events that I have written already...

Heavy footfalls announced someone's entrance. Glancing towards the sound, she saw that Edmund had joined their little group. He took a seat next to hers. Behind him was another man, presumably the host, who went directly to the windows on the western side of the room. He neither sat nor spoke throughout the evening. The day passed, the people eventually scattered. Ardellia and Edmund left for their apartment, with their son and her young brother following closely. In her room, Ardellia was not quite sure of what to do; it was far too early for sleep and the new atmosphere 's unfamiliarity had her nervous and filled with anxiety. She wandered outside and into her husband's room.

"How long are we staying?"

"I am not quite certain."

"Well what of the business proposition?"

"It is fine, all is going quite well." He answered flippantly,

"And what exactly does superintendence entail?"

"Paperwork, archiving, keeping properties in check."

Ardellia needs to comment on their host's insulting behaviour.
