As far as David Thompson was concerned, even leaving aside the fact that Aria Grant's identity would make him side with her, the order of who spoke to him first, between Aria Grant and George Flack, would make him listen to Aria Grant anyway.
"If Mr. Flack says so, then I definitely have to follow his advice, I've always felt guilty towards Mr. Flack. But I am worried about one thing, after all Mr. Flack has been waiting in the company for such a long time, even if I didn't tell, what if Aria Grant finds out, you also have to think of a reason!"
David was thinking that he could not explicitly agree, and then when the couple quarreled over this matter, blame him. That would not be worth it. Moreover, David cleverly thought that he hadn't said anything, he hadn't stated that Aria Grant already knew, nor had he told Aria Grant about this matter. It all seemed to be handled just right.
