Bill hurried through Diagon Alley with a single shopping bag that looked rather empty to the eye of a passerby. Little did the bystanders know, the bag was exceptionally full, to the point it was threatening to break the expanding charm Bill'd performed on the inside.
Trying to remain unnoticed, he'd spent the better part of the afternoon in a Muggle district shopping buying clothing, toiletries, food, and other supplies necessary for housing three teenagers. With the purchases stowed at his side, he was back in Diagon to pick up a few medicinal potions along with some pumpkin juice and other non-Muggle food essentials. Final purchases complete, he ducked into a nearby alcove between two shoppes and Apparated home to Shell Cottage.
Voices came from the kitchen and he ducked inside, setting the bag down on the ground and coming up alongside his brother Ron. He was still so relieved and thrilled to see the group that he slung an arm around his youngest brother and gave him an affectionate half-hug.
"Cheers," he said. "I brought clean clothes and some potions. Hopefully no one who knows I live with one other person noticed I was buying enough for a small army. A small, healthy, and terribly fashionable army at that."
