Elliott, it's a long story and you literally needed to have been there; I don't think it's possible to explain otherwise, even with context, without it sounding weird. Yeah, I presume that he would have thrown Peter out of the window for hitting on Brun in such a crude way.
Y'know, I find myself wondering if this is the first time that Brun has seriously had a lot of money to spare. Understandably, a part of her desperately wants to use this opportunity to have all those experiences that she's long dreamed of but has never been able to afford!
