The three of them walked up the front steps and stood in front of the door. Ron and Harry didn't move forward, as they were waiting for Hermione to push the doorbell first, except she stayed still.

"Hermione, there's a doorbell… if you want to press it," Harry asked.

She pursed her lips together. "What if…" she pondered.

"What if what?" Ron asked. He had considered pushing the bell for her but thought better to wait until she was ready.

"What if… they're not home?" she asked.

"Then we come back tomorrow?" Harry suggested.

"What if they're on holiday?" she thought.

"They have already come to Australia! They need another holiday?" Harry asked, surprised.

She stared at him, unimpressed.

"Sorry, but you have got to admit, this is pretty different from England. It's warm and sunny… and everything we've seen of this country so far feels like a holiday," Harry said.

Hermione didn't say anything, just kept staring at him.

"Except that it wasn't a holiday and it was for your parents' protection," Ron said hastily, trying to save Harry from digging a hole for himself.

"Thank you Ron," Hermione turned to Ron, which saved Harry from a lecture. "But what if they are on holiday?"

"They're not. You said you rang ahead and it was definitely your father that answered the phone," Ron told her.

"Or more importantly, what if I can't do the spell?" Hermione said.

"Hermione, you know you can do it," Harry said.

"Or what if this was a mistake? Coming here? What if they don't-"

And suddenly, without warning, the door opened and a tall woman, somewhat haughty and thin (who instantly reminded Harry of Aunt Petunia) stepped outside holding the hand of a young boy who was breathing heavily, sobbing loudly and tears spilling out of his eyes. This was definitely not what they had expected to see.

"Thank you so much Monica, of course, little David will be fine!" the woman called over her shoulder. "Thanks again, yes, we'll catch up soon, ladies lunch next week!"

"It hurts Mummy, it hurts!" the boy wailed loudly.

"Oh David, you'll be fine, ooh sorry!" David's mother had stepped smack bang into Harry. "Sorry love, didn't see you there! Not as painful as it looks, right?" she smiled, then quickly turned back to her son. "David, you'll be all right, you'll be all right."

David was red in the face, bawling his eyes out, definitely not looking all right.

"Come on, come on…" Hermione watched as David's mother bundled her son up into her arms and patted him on the back. He was still crying as she carried him and walked outside the gate. The scene seemed so foreign and yet, was strangely familiar at the same time.

"Hermione, what's the matter?" Ron asked.

"I'm just looking…" Her eyes wandered over the neatly trimmed lawn, then the driveway and then spotted the small, shiny plaque next to the door that somehow all three of them had managed to miss.

Dr Wilkins – Dental Surgery

Despite the fact that Hermione had cast the spell on her parents and altered their memories so that they would suddenly forget they had a daughter and have a newfound, overwhelming desire to move to sunny Australia, some things hadn't changed after all.

Including the fact that Harry's hero complex had kicked in again. He took a step inside the house before Hermione and Ron could say anything and go into the house first.

"What's going on here!" he demanded.

Oh no, she thought. Mistake number three

"Harry, wait!" she called out.
