Audrey had been rather nervous as to how George would respond to the news. It was a lot to take in, his baby sister being the second Weasley child to give Mrs. Weasley a grandchild. Hopefully George would be excited for her, and not... angry or upset. She squeezed his hand in return, then let it go so George could go hug his sister if he wanted to.
"Congratulations, Ginny." Audrey said, giving the redheaded girl a smile. She was still a little nervous about George's response. Of course, they could talk about it later if George needed someone to talk to about it all who wasn't part of the family.
