Author note: Sorry not an update, just realized I wrote he was in 6th year not 5th year, sorry. Although seeing as I am writing the next chapter right now it shouldn't be long for an update.
Buffy sat next to Giles who in turn was mumbling under his breath about the woman standing at the back of the classroom. Buffy just raised an eyebrow before watching the first years enter the classroom.
She hadn't had a chance yet to talk to Giles about the situation but she figured they had a break after this class so it shouldn't be a problem. Funnily enough this was a Gryffindor Slytherin class which meant she had her brother and sister for her first class. Unfortunately her last class was also Gryffindor and Slytherin but 5th year which meant she had Harry last.
She sighed and peered at the text Giles had opened to and shot him a knowing grin before saying "So am I taking this one?" Giles looked at her gratefully and said "Would you? That blasted woman keeps trying to undermine me." Buffy shrugged and said "Not like I don't know the subject and Snapey taught me some useful stuff." She then turned to the first years that had finished coming in and had taken a seat.
She shot Dawn and Cayden a look before saying "alright then, today we are going to be studying Vampires. Apparently seeing as how this is your first year and Dumbledore has informed us of Vampires being the forest you guys need to know this stuff." Buffy nearly rolled her eyes, Vampires in the forest well duh.
She smiled at the shocked gasps but stopped at the "hem hem" sound and looked at the lady in the back before saying "If you need to cough I would suggest leaving the class room." She turned back to the students and said "Ok I am your assistant teacher but me and Professor Giles here have our specialties, one of mine is vampires. I'm Professor Summers, but call me that and I will be forced to hex you so call me Buffy." Another "hem hem", Buffy looked up at her again and said "Does that mean your leaving?"
Dolorous Umbridge was annoyed but she said "I believe the students are supposed to call you by your surname, and there is no proof to vampires is the forest." Buffy's eyebrows shot up and she said "Right well one, my classroom, my rules, two can you tell me for a fact there isn't vampires in the forest and lastly if you keep interrupting this lesson, they won't learn a thing." Buffy smiled when Dawn giggled behind her hand and half the class was looking shocked. She turned back once again to the class clearly not expecting an answer and said "Ok firstly what do you know about Vampires?"
About 10 people raised their hands and Buffy pointed to a Slytherin student who said "They can't go out in the day light?" Buffy nodded and said "5 points to Slytherin. What else?" A Gryffindor answered "They don't like crosses." Buffy nodded again and gave her five points before saying "Right, but what kills them?" She pointed to a timid in the back "Stake in the heart." Another five points to Gryffindor.
All seemed to be going well considering it was her first class. Well that was until they got to the part where Buffy wanted to teach them how to produce a ball of sunlight. At this stage Umbridge stepped forward and said "I believe if you read the syllabus, the students are not supposed to be doing this until their fourth year." Buffy merely looked at her calmly and said "That is your second warning about interrupting a class I am teaching, one more and it might turn drastic."
Buffy shot Giles a look at his snort before turning back to the class and proceeding. All in all the class seemed to go over well and Umbridge kept quiet mostly and writing in her note book furiously. Buffy ended the class with a wave of her wand creating a flash of sunlight and proclaiming "And that is what you will achieve by the end of this semester, have fun in your next class."
Cayden and Dawn hung back for a few seconds to tell her it was fun before telling Buffy they had to go do their homework in the library during their free and Umbridge followed them out. Buffy then turned to Giles and said "So we have a free, I need to talk."
10 minutes later
Buffy was sitting across from Giles with him holding the letter. He was looking as lost to what to say as Buffy felt. She finally cleared her throat and said "So do I tell them? Or you know just let them going on believing that Hank is their father?" Giles took his glasses off his head for a minute before putting them on again and looking in the face and said "I think they have a right to know, but it is entirely up to. Would you want to know if you were them?" Buffy sighed and said "That is so unfair. You know I would but they are 11 years old, how will they react to this?"
Giles leant back on his chair and looked at her seriously and said "I think they are both mature enough to handle whatever you tell them. They respect you and look up to and will trust whatever decision you decide."
Buffy nodded and put her head and rubbed her temple. Giles said in a softer voice "Something else is bothering you?" Buffy warily lifted her head and said "Well yeah. I mean we have this whole key, Glory, adopted thing going on but on top of that I find out that my Harry is apparently living here in the magic world."
Giles looked at her surprised and said "Wait Harry? You mean Harry Potter is your Harry?" Buffy looked at him confused and said "Well yeah what other Harry would I be talking about?" Giles shook his head and Buffy heard him mutter "That's why he was talking to Dawn and Cayden at the feast." Buffy's head up and she said "Wait! Cayden and Dawn knew Harry was here before I ran into him?" Giles looked slightly embarrassed and said "ehh…" Buffy however stood up and said "Oh they are in so much trouble. You said you've got the next class right? I'll be back for the sixth grade class." Before he had time to answer she shot out of the room.
Library
Cayden and Dawn were working on their potion essay, well Cayden was whereas Dawn was complaining about using the quills when Buffy came storming into the library.
Her face was red and her eyes had more brown in them then green making the twins shrink back a little. She said in a quiet controlled voice which made it scarier "Dawn Marie Summers, Cayden London Summers, Did you forget to tell me something since I have been back?"
Dawn looked at her brother and shrugged and said "Um no?" Buffy turned to Cayden who looked thoughtful before saying "Oh and the fact that my once best friend goes to Hogwarts isn't something to tell me is it?" Both children's faces seemed to drain of color at the words of their sister and both were staring at her with looks of alarm on their faces. Buffy took a deep breath and said "Well are you going to say something?" Dawn softly said "We uh kinda haven't had the chance..." Cayden continued "We thought we would be able to tell you on the night you came back but ..." Dawn continued "you came back early and we kinda forgot. Plus kind of busy here… Why didn't Giles tell you I mean he knew about the boy who lived I mean how could he not cause his brother hates him."
Buffy closed her eyes for a second recalling conversations she had with Giles before saying "I think I have only ever called him Harry to Giles. So no reason to blow a gasket at him." Cayden said in his ever observant voice "That is really clear headed of you sis, anyone would think you're growing up." Buffy shot him a glare before saying "That is professor Summers………(smiles) nah, makes me sound old. I suppose I better go get ready to teach Harry huh?"
Buffy got a few steps before she felt a tugging on her sleeve and found Dawn holding her. Dawn said in a careful voice "Are you going to give him his letters?" Buffy looked into her sister's bright blue eyes and said "I don't know Dawnie, he didn't even give me a chance the other day. Just accused me of being evil. I think maybe we drifted apart a little too much over the years, changed. But don't worry about it, yeah, you've got potions and professors to annoy."
Buffy watched as her sister joined their brother at the table. She stood there for a few more minutes before shaking her head and turning to get ready for the inevitable clash of personalities.
Author note: Sorry I didn't get to the Harry Potter Clash yet but seeing as how she is teaching him next lesson I gotta figure that he has to irk her in some way. As will Umbridge especially if maybe Harry insinuates that Buffy can't teach them a thing. Hint Hint. I know you guys are waiting for the whole clash thing but I can't just throw that in ya know. I hope you like it though and ewww Fudge and Joyce me thinks not. Sorry but no. Oh and there is a reason Giles and Buffy don't know who the dad of the twins is, just so you know.
