Harry's POV

When Hermione got back to the common room she was acting, strange. When we asked her about what Dumbledore wanted she just said it was nothing but I could tell she was lying. We pestered her about for a while until we gave in. Then we started talking about the exchange students and Hermione went all ridged

'I, umm, don't think that we should look into the exchange students anymore'

'What's got into you Hermione, what if they are death eaters, and Percy said that he had killed'

'yes but he didn't say what he had killed, and I think that we should trust Dumbledore, his judgement has been right so far, and if they were death eaters he would not let them so near you Harry' and with that Hermione stormed off to bed

'She knows something'

….

The next day we had care of magical creatures, Ron and I got there extra early to see if we could talk to Hagrid beforehand, Hermione hadn't been at breakfast, in fact we hadn't seen her all morning.

We got down to Hagrid's hut but he didn't seem to be there. About 5 minutes later everyone else arrived including Hermione and the exchange students, we were about to go talk to Hermione when Hagrid came out of the forest

'Now today we will be 'Hagrid started

'Excuses me Professor Hagrid' Percy said 'Is there any way I can say hello to my pet dog I haven't seen her in ages'

'Don't tell me Mrs O Leary is here' Thalia groaned

'Yep' Percy replied popping the p

Mrs O Leary was just and dog what had I been so worried about

'Umm, well it's a little unorthodox but okay Mr Jackson, it is a creature and this is care of magical creatures, maybe today instead we could look at more normal animals' Hagrid replied, there was a groan from the Slytherin's who were almost all Purebloods

'Thank you, and she isn't a normal pet by any stretch of the imagination. Mrs O Leary heel' Percy shouted

Then a massive dog bigger than Hagrid appeared, it had gigantic teeth capable that filled a huge mouth capable of swallowing the whole class in one (okay maybe I am exaggerating a bit) and red eyes that reminded me of Voldemort.

'She's beautiful' Hagrid said, he had always had a thing for monsters which this thing defiantly was 'What is she'

'She is a hell hound'

'She can't be a hell hound' Hermione piped up 'they don't exist, they are a myth'

'And wizards aren't' he had got Hermione there

'But . . . 'it was nice to see Hermione lose an argument even if she was my friend

'Where in the world did you get a hell hound' Ron asked

'In hell of course, it sort of comes in the name' I had to laugh it was such an obvious answer

'But hell doesn't exist' said a Slytherin kid who I didn't recognise, as he said it thunder boomed in the distance, that was odd it was a clear day.

'Says who, have you been and with that kind of blaspheme I could put you there in a second' Nico said with a look of pure hatred of his face, seriously if looks could kill this kid would be worse than death

'Don't worry Nico, these mortals just don't understand' said Percy, mortals he had defiantly said mortals, like he wasn't. I looked at Annabeth who was behind Percy giving him a dangerous look. Mortals, why mortals?

'But it's frustrating, you don't have them saying he sea doesn't exist or Thalia the sky doesn't exist' now Annabeth was looking at Nico. The sea and the sky what do they have to do with hell?

'Anyway ' Hagrid continued but for me the rest of the lesson was a daze, everything we found out about the exchange students just created more questions. Who are they?

A/N: It's a bit rubbish but the next one will be better, I hope, fingers crossed
