Any changes made to the Burrow must have been minor, because to Molly it still looked the way it had when she had been pulled there from her timeline. She wasn't surprised there were no children's toys lying around, considering all of her children were grown adults at this point. Toys weren't generally a part of adulthood, after all. At least she could have the peace of mind to know her children had all grown to be self-sufficient and successful in their own rights.
For the most part, Molly had puttered around the Burrow since her own release from quarantine. It was easiest for her to go back into her own routine rather than trying to find a new one. Mama Weasley did not like change and if she had to deal with her children being grown, she would simply go back to taking care of the house. Molly ws also glad to have Jo around, because it felt like she had gained a daughter out of this strange situation. Ginny was off with Harry and Molly hadn't had a chance to see her little girl grow up. She would take an extra daughter any day.
She had gone about, cleaning up here and there and allowing the last of her Christmas jumpers to finish knitting as she did so. The usual sound of scrubbing could be heard from the kitchen. Molly had gone upstairs to put away a load of clothes when she heard a voice call out. "Be right down!" she called back, appearing moments later from the direction of the staircase. "Percy. Hello, dear," she said with a smile as she closed the space between them to pull him into a hug.
