Just to explain, I know Dawn should be older but I'm making her 14 so she can go into 4th year with Harry. Also I apologise for the similarities with book 2 I just love the bit where Harry ends up in Knockturn alley. So please read enjoy and review!
"Remind me never to do that ever again" Giles moaned clutching his head as he hit it on the mantelpiece whilst climbing out of the fireplace. He looked with disgust at the soot on his clothes and began brushing it off. "I knew there was a reason I disliked it."
"Giles Dawn's not here."
Giles groaned, "I should have known, nothing will ever be easy with you two will it?"
Buffy pulled a silver knife from somewhere and pointed it towards the fireplace. "I'm gonna kill that guy, then get some answers. I should have known I couldn't trust a headmaster, just hope he turns into something small…" Buffy would have continued to rant had Giles not interrupted.
"Buffy Professor Dumbledore is not going to turn into any kind of animal or demon, its professor McGonagall who you want to, and Professor Snape's you're snake man…Albus."
Professor Dumbledore stooped to enter the room, quickly took in Buffy's knife and stance and sighed very softly.
"Ok buddy what have you done with my sister? You may be some big shot wizard but I've got some pretty nifty slayer tricks." Buffy fell silent, she had only known Dumbledore a short while and already she was beginning to calm down in his presence. His blue eyes remained trained on her face as her breathing returned to normal.
"Dawn has probably simply missed the fireplace. She is in all likelihood very nearby probably within the castle."
"Whatever, just get her back here unless you want that wand somewhere…well can we find her…please" Buffy finished in a small voice as Giles glared at her and Dumbledore's eyes widened ever so slightly. 'Well well' he thought. 'This is going to be an interesting experience.'
After spluttering on her mouthful of ash Dawn was spun quickly away from Sunnydale. She tucked her elbow in tightly as a sharp pain travelled up her arm. She glimpsed flashes of brightly lit, cozy rooms but after only a few seconds fell out of a strange fireplace onto a cold stone floor.
"Merlin's beard" a booming voice shouted as she looked up. What Dawn saw almost made her pass out, and that was pretty difficult given all that she'd seen in the last year or so. The man standing over her was enormous, so big that he looked as if he shouldn't be allowed indoors and the bushy hair and beard did nothing to detract from this fearsome image. "Who the hell are you?" the giant boomed. Dawn could only manage a squeak in response. "Wassat? Oh Hogwarts are yeh?" Another squeak from Dawn. "Yeh must be one of them Summers kids, guess I'd best get yeh to Dumbledore then hadn't I. Just give me a mo to finish me mead." With that the giant downed a huge gulp from the massive tanker infront of him and grabbed Dawn by the collar, hauling her to her feet. She gasped as hands the size of spades brushed soot from her shirt and cropped jeans.
"Who-who are you?" Dawn finally managed to squeak. Experience had taught her that this question was second only to Buffy's "Are you evil?" when faced with the unknown.
"Galloping gargoyles how stupid of me. Rubeus Hagrid, keeper of keys and grounds and care of magical creatures teacher at Hogwarts. Call me Hagrid. You mus' be the little 'un, gonna be in harry's year I reckon, you'll have to keep on yer toes wi' that lot around. Ah well bes' get yeh to the castle afore they send out a search." Hagrid marched out the door carrying Dawn's trunk as if it was a featherweight leaving her to run behind him wondering what on earth was happening.
"Buffy do calm down." Giles attempted to restrain his slayer as she fought to go straight out the office door and ransack the entire castle until she found her sister. "The castle is extraordinarily large, it is not practical to simply run around it, besides which Dawn has a knack of falling on her feet,"
"Yeah right onto musical demons and hell gods and…giants."
"Buffy really, Dawn has never met any giants." Giles turned as Buffy brushed past him just in time to see her brandish a knife at the pocket of a massive overcoat. Not daunted by the considerable difference both in height and stature between herself and the overcoat's wearer Buffy demanded that the newcomer let her sister go.
"Miss Summers it is quite alright. This is Hagrid, you will be seeing a lot of him in the near future. Hagrid I am extremely glad that you found Dawn safe and sound perhaps you could put her down now." Hagrid looked down and found that he was indeed holding Dawn behind him in a protective manner that was having severe implications for Dawn's circulation.
"Right yeh are professor, sorry 'bout that." He mumbled looking sheepish. "You alrigh' little 'un?"
"Fine, fine I'm good." Dawn stammered once again finding her breathing obstructed, this time by Buffy's bear-hug.
Where did you find her Hagrid?" Giles rushed forward to shake the giant's hand.
"Rupert, good ter see yeh mate, good ter see yeh. This one of yours then? Found her flat on 'er face in the Three Broomsticks, saw the trunk and figured to bring her here."
"Well that's a relief I must say," said Giles and Dumbledore nodded in agreement.
"Yes I was slightly worried she had ended up in the shrieking shack. I really must take it off the floo network."
Buffy decided that enough conversation had passed without her understanding for one day and opened her mouth to interrupt the conversation. She soon closed it again having no idea what to ask first. She repeated this process a few times until Dawn ventured to comment, "Buffy I wouldn't plan on turning into a goldfish on land." Buffy shook herself both mentally and physically,
"Right, yep uh just wondering…what happens now?"
"Well dinner is at seven, I thought I would take you to your rooms and let you settle in before that."
"Right. Good. Very good." Buffy was very curious to know what had happened to her ability to speak coherently. Jet lag she figured but could you get jet lag from a 5 second journey? 'Man this is wiggy' she thought as Dumbledore led the way out of is office, floating Dawn's trunk ahead of him.
