Barrel gave her a small salute.

"Yes, ma'am," he said, before turning to Agatha. He did have to try to keep her distracted too, after all. Barrel gave her a little smile. "Besides. It's always more fun when you're learning with someone."

The bell rang again as someone else entered. Aggie turned to see who entered.

"Witches' shop, the best bargain in--"

Barrel knew by how Aggie deflated who had arrived.

"Oh," the taller witch said. "Hello, Shock. Hello, Carver."

Aggie turned to Barrel with that stern look. He held up his hands in defense again.

"I-I didn't know she was coming in, I swear!"

Shock glanced at the shelves to try to find the swamp smoke, then ran a hand through her hair to subtly pawn Loki from her ear.

"Relax," she said. She pulled off her backpack and held it up. "I'm just here to make a delivery, then I'm off."

Aggie gave her a suspicious nod, then called to the back. There was no way she could keep an eye on the three of them by herself.

"Agnes!" she called. "Scorpion delivery!"

In the few seconds Aggie turned away to call for the smaller witch, Shock set Loki on the shelf while Barrel blocked Agatha's view. Agnes quickly came from whatever she was doing from the back to crawl up to the counter. By this point, Shock held a bottle and read the label - one away from the swamp smoke - then put it back in a calculated ploy in case one of the witches saw her reaching for the shelf.

Just a customer looking at the merchandise, even if an unpleasant customer. Carver would have to signal to Loki which bottle to push, but she could do that easily.

Shock walked up to the counter with the backpack and carefully set it on the counter. She didn't need to say another word as she started pulling jars and bottles from it, while Agnes took inventory of what she had and calculated payment. Both of them were so used to this routine that they didn't bother with small talk. Barrel tried to keep Aggie and Agatha focused on him.

"So, uh, about what we discussed," he said. He tried to play it off as keeping this on the down low with his older sister right there. "You're [i]sure[/i] beetle's eyes aren't a good substitute for spider eyes? They seemed similar enough, but I don't want to ruin the recipe..."
