Weasley family

Yori is Ron's twin sister. She's currently 15 years old, and it's August, so next month Fred (17), George (17), Ron (15), Ginny (14), and Yori will be starting a new school year. Tonight, Molly had invited Bill, Charlie, and Percy to dinner, as they no longer lived at the Burrow. Fleur, Bill's wife, was also coming. They were surprised and wondering why they'd been invited as well. At the beginning of dinner, Molly and Arthur seemed nervous, and the other siblings were curious about why their parents were so anxious. A little while later, Molly cleared her throat and spoke.

Molly: Sons, daughters, Fleur, it's hard to say, but I'm pregnant, again.
