There it was, the proper faltering that usually led up to something like being asked out? Or maybe being asked something else. Something that made him uncomfortable apparently. But he was babbling about how pretty she was so things were looking somewhat hopeful? She didn't question him, nor interrupt. She was very eager to find out what it was he was trying to say, but didn't want to rush him.
Her eyes widened slightly at his confession. He told his mother they were dating? Well, that made things a little weird, that he would say that before asking her if she would. Eden probably would've mentioned that if it weren't for the part where she'd been invited to dinner with his mother and apparently they were supposed to be dating already.
While she liked Rene, which she did, and thought this was sort of a date, which is why she cleaned up so nice, this was all really weird. "You want me to pretend to be your girlfriend while having dinner with your mother?" That is what he said, right?
