Roger almost jumped up in surprise, which would have left George meeting the floor in an ungraceful leap. He managed to catch himself before doing that, out of sheer stubbornness to prove something to George, even if he wasn't exactly sure what that something was now.
Instead, he placed his free hand on George's hip and held him still as possible, despite how uncomfortable it was having George on his lap. Whether he was uncomfortable because he didn't want George on his lap or uncomfortable because he liked it, he wouldn't tell.
Clearing his throat before speaking, he asked, "Verity's pregnant?" It was news to him, but that would explain her moodiness. Or maybe that was just because she seemed to dislike him. His wondering came to a screeching halt at another realization.
