"Oh," said Raine, taken off-guard, when Rue's intent became apparent. She hadn't known what to expect, but if forced to guess, she would not have been anywhere near this. "This is-- this is lovely. Why...?"

It didn't make sense, said the suspicion following immediately on the heels of the startled delight. She herself barely knew Rue, and judging by their conversations beforehand, Solomon and Rue weren't on the best of terms. And this most recent 'understanding' could hardly have generated this; Rue would have had to prepare this beforehand. Nor could it have been Valdis' handiwork.

In other words, Rue had done something kind for the couple specifically, rather than one of them separately, and Raine couldn't see why he was at all interested in their relationship.

She stopped herself from frowning dubiously at Rue, and instead took Solomon's arm, since they had both been set adrift. "Thank you," she said, polite, "but I have to wonder why you went to the trouble to set up a-- a date for us."
