It was a rather sunny day on the Hogwarts grounds, a nice treat for her students, even if they were avoiding the Dementors circling the grounds.

It was while the students were all in their lessons that something strange happened.

On the outskirts of the forbidden forest, a blue box began to appear. It sat there for a few minutes after it had finished materialising and then the door was flung open.

"Doctor, where are we?" questioned the woman who had just walked out.

"Oh, let's see, shall we?" the Doctor muttered as he walked out behind her, closing the door as he went, "Big castle, spooky forest, oh, nice lake."

He walked around the area, and his companion followed, looking around as they went.

"Oh, there seems to be some sort of pitch, I wonder if-"

"Oi, how'd you get 'ere?" questioned a very large and hairy man.

"Oh, I apologise, we seem to have gotten lost, could you tell us where we are?"

The man blinked down at them, "Well now, 'ow d'ya get lost an' end up a' 'ogwarts?" he muttered, before looking over to the castle, "C'mon then, I reckon tha' Dumbledore woul' be interested in this."

He walked away, clearly expecting them to follow, the Doctor shrugged and followed after him.

"Come on then, Rose, let's keep up," he stated, "Before he accidentally leaves us behind."

She looked at the giant of a man's legs before jogging over to them.

They entered the castle and stared in awe as they walked, paintings moved and talked as they went down the hallways, often pointing over at them.

As they were walking, the classes let out and their paths were flooded by children and teenagers, all rushing about. Some of them looked at the two strangers before shrugging it off and continuing to their lessons.

A corner was turned, and the Doctor froze in shock.

The feeling was weak, but it was there and familiar. His eyes zeroed in on a small figure walking down the hall, sandwiched between two other people.

He didn't realise that he was shaking, nor that his eyes were filling with tears. He knew that child, he had been the subject of many of his nightmares and sleepless nights wondering what had happened.

"Zeta?"
