Eddie waits patiently at the counter. Aristotle hasn't left the jar yet, but it doesn't seem to bother the little octopus any. He just mutely rocks the glass container back and forth, holding his quill.

"Perfect. And yes, I figured precautions were probably wise." To say the least. It is allegedly cursed specifically for muggles, but it's not worth the risk. Especially given it is entirely possible the person who bewitched it might have seen those of mixed muggle blood to be more or less worth the same thing, really. He produces a leather wrapping along with the required coin. To say he is precise and careful when looking the book over is an understatement. After a moment, he nods. "It'll be a lovely addition to my collection."

Aristotle just waves the quill around from inside the jar.

"You should give that back to her, you know. It's polite," He chides the octopus. Any attempt at moving his hand near the quill only end in him getting poked with the quill nib, however. He eventually gives up and frowns at the little invertebrate. "Well, fine. You can keep it, then."

He absentmindedly rubs his hand where he'd been prodded, turning back to Caroline. "Looks like I'll be... ah, purchasing the quill as well."
