Terry blushed, and shook his head. "I haven't actually figured out how to meld Muggle technology with magic, the metal detector was defunct, so I just used the wires to direct the magic." He shrugged, and grinned sheepishly.
"Though I hear people have successfully charmed auto-mo-biles to fly." He brightened. "I'd love to have a flying car, much more comfortable and safe than a broom." He grinned. "But I'd love to do more work with Muggle items, so I'll see what I can do. For you."
He could see that Ernie was still a little uncomfortable, and didn't say anything else except, "I mean it. And you're welcome," before pressing himself against Ernie's side as they walked.
Terry beamed as Ernie mentioned taking Ben out, and nodded. "Alright then, that sounds great." He smiled. "So, shall we?" he nodded towards the castle's entrance, and they walked towards it.
Terry fumbled a little with the unfamiliar Muggle money, but they managed to pay the entrance fee, and were given brochures and strange little devices which Terry had no idea how to work. Terry opened his brochure and found a map, twisting and turning it to try to make it make sense.
