At the sound of the voice, Dominic sat back on his heels and looked around. He'd not even noticed there was anyone else in the room when he'd walked in - but now that he looked he recognised the man who'd spoken. Recognised his face, at least. He couldn't call his name to mind, if he'd even known it. He smiled. "A spell sounds great. You'd think, after a decade, I'd stop having moments where I forget I've got a wand..." He huffed and pulled himself up into a chair, gesturing to the bookcase to encourage the customer to go ahead.

"You think I'll be able to fit all these on?" he asked, waving at the stack of books he'd brought with him. "I don't want to have to take them home with me, and Seamus will give me his 'how could you?' face if I leave them on the floor."
