Disclaimer: I do not own Harry Potter or Twilight

A/N This is the last pre-written chapter I had and I'm still in NY til after Easter. If I get a chance to spend more than a minute on a computer than I will try to write more for ya'll. Thank you for your patience and understanding!

When we got to Hogwarts I was introduced to the other teachers. Snape was assigned my 'tour guide' by Dumbledore. He showed us, Riley my guardians and me, to our rooms. He than showed me to the DADA classroom so I could get acquainted with everything and start my lesson plans.

That was all yesterday, tonight the students will be arriving back from break and I will be introduced along with Potter's protection detail. I decided I wanted to make a real impression on everyone tonight so I through my hair up in high pigtails. I put on my usual shredded black cargo pants and some black combat boots. On top I wore a tight black tank that ended just above my belly button showing off my scars. I figured I could scare the kiddies a bit for some fun.

Riley was going to skip dinner and Abby and Chan were going hunting so it was just me and Snape headed to the main hall. I had my black robe tossed on and skipped my way next to Snape as he started leading the way. I was feeling especially giddy and I made it known, Snape just shook his head with a small smile on his lips.

"C'mon Sev, don't wanna be late to meet all the kiddies do we?" I laughed as I skipped circles around him twirling like a child every now and then.

"Calm down Isabella. We are already late because you kept trying to make me wear that horrible yellow robe. Really it's your fault." Ha, he's right; Trixie and I had actually bought him and Lucius a yellow sparkly robe and tried telling them it was the new black. It didn't work as well as I had hoped.

Finally we reached the doors and Snape opened them walking in first. I was stunned just gaping at the ceiling. It looked like an actual sky. I didn't realize how quiet the hall had gotten. I skipped over to Snape again and tugged his hand bouncing in place.

"Oh, look Sev! It's beautiful! Holy fucking hell! I am so going to do this to my room at home! O look, it's Draco!" I said as I noticed the younger boy smiling at me. I skipped over and gave him a kiss on the cheek causing him to blush as I messed his hair slightly. "How's my favorite nephew!"

"Hey aunt Iz, what ya doing here?" Draco started to ask me. Before I could respond we heard a throat clear. My head snapped to the main table where Dumbledore was seated with the other teachers. I pat Draco's head before turning to skip to the main table and take my seat next to Snape.

Dumbledore started to speak, "attention students, this is your new DADA teacher for the remainder of the year. Professor Ophidian. Please make her feel welcome." Dumbledore sat down again as conversation resumed.

I had eaten my fill and decided to gaze around the hall. I found Potter and can you believe my surprise when I noticed who his protectors were? The fucking Cullen's. I started to growl and all 5 of their heads whipped towards me. Rosalie and Emmett looked ecstatic. Alice looked scared and angry. Jasper looked guilty and relieved. Edward looked hopeful. My growls continued until a glass shattered. I didn't even realize I was squeezing my pumpkin juice that hard.

Snape leaned towards me placing a hand on my shoulder and whispered for me to calm down. "Relax Isabella; you don't want to cause a scene. I didn't realize these vampires were the ones you knew I'm sorry. There are 2 more with Madam Pomfrey in the medical wing. If you would like we can discuss with Dumbledore on keeping them away from you although unfortunately when Potter is in your class they will be too." That gave me an idea of using them as test dummies in class. I smiled towards Snape.

"No worries Sev, I'm good now. Having them here is perfect, it means I don't have to go find them," I smirked to Snape who knew exactly what I meant. The Cullen's continued to stare at me the rest of dinner. After dinner I retired to my room and talked to Riley a bit before going to bed.

The next morning

Yay! My first classes today! Riley will be sitting in the back observing the class. Abby is imprinted on me and Chan said he would stay in his snake form. He enjoys scaring the kiddies as much as I do. I wore a low cut tank and pulled my hair in a high ponytail so everyone can see Abby on me.

I am sitting at my desk with Chan curled up around my feet. Finally students start pouring in. Today I have Slytherin and Gryffindor, yay. On the plus side Draco is in this class. I clap my hands twice to get everyone's attention.

"Alright class! My name is Professor Isabella Ermelinda Ophidian, but please call me Izzy," I smirk at the Cullen's knowing they probably want to call me Bella, but Bella died a long time ago.

"Today we are going to learn about vampires since we seem to have so many in attendance," I point out the Cullen's and than Riley. Everyone turns to Riley, including the Cullen's. Since he has no scent and has learned to block his mind off, no one knew he was here.

I continued the class, letting them know all about the cold ones and the originals. It seemed the Cullen's didn't know about the different kinds. I told the class after they break for lunch we would learn different ways to defend ourselves from vamps without outright killing them. I was staying here for lunch as I had brought an apple and water bottle with me. I also had a stash of blood pops in my desk for Riley.

"Here ya go Ri-man, something for you to suck on," I giggled as I tossed him a pop.

"Ha-ha very funny Iz," Riley laughed sarcastically but I could tell by his smile he was just kidding.

"Bella?" a voice behind me pulled my attention from Riley. I turned around and came face to face with five of the Cullen's. I plastered on my crazy sadistic smile.

"Why hello Cullen's, don't you have a child to be watching?" it was Alice who spoke to me first but Jasper was the one to answer me.

"Actually, Izzy," I was happy to hear him use the name I told them to, "Carlisle and Esme are with him now."

Alice took over from there, "what are you doing here Bella?" god, what doesn't she understand about calling me Izzy? Well, time to use some of the nicknames I have for them. See how they like it. I smirked as I replied.

"Well pixie twit, since you seem so curious, I am a witch. After being tortured for 4 years because you're fucked up family left me for better pets, I was rescued by some unknown robed figures. Turns out I am a pureblood who wrongfully had my magic binded. Ooo Major Dick! I totally can give you a run for your money now," I smirked at Jasper and dropped my robe on my chair showing off my scared arms.

"Don't worry, I have more but I'm not in the mood to strip for ya'll," I winked at the shocked faces while Riley snickered next to me. Riley decided to use his voice and join our conversation.

He pointed to the one positioned on my collar bone. "That one is mine," he smiled.

We heard a growl and just as Edward was about to pounce, Chan slithered out and stood in front of Riley and I for protection. My joy increased and I could tell my strong emotions were starting to get to Jasper as a grin found a way onto his face.

Edward stopped where he was but stayed in his crouch. He finally decided to grace us with the voice I once found musical, now it just made me want to gag.

"Isabella love, slowly step away from the python. I can protect you over here better. No sudden movements."

"Is this guy serious?" Chan hissed to me causing Abby and me to giggle though no one heard her. I walked toward Chan and rested my hand on him.

"Relax Chan, I have a shield on my brother, no one can get within a foot of him that I don't trust," I hissed to my guardian calming him down. He slowly slithered behind me and toward Riley who was smiling at the whole scene. The Cullen's were just gaping at me once again.

"You know sister, if this is the reaction to me biting you once, we should definitely tell them about our playtime with PC. I don't think I told you how much I liked that name. Anyway, I'm sure PV here is curious of that," Riley nodded towards Edward signaling who PV was.

"Bell… I mean Izzy, what's with all the names? What do PC and PV even stand for?" Barbie Bitch asked. Hmm I like that, BB. I smirked again to reply.

"Well BB, which by the way is Barbie bitch, PV means pussy vamp. O shut up PV you totally are a wimp and you know it," I said to Edward when he started growling at Riley's snickers. "Pixie twit is pretty self explanatory, along with Major Dick. PC was my lovely owner for 4 years. Right after your bro from another ho over there ditched me in the woods after telling me I was a toy ya'll never loved and got bored of, I was picked up and brought to Victoria, who incase you're a little slow on the ball, is PC. She didn't seem too happy ya'll went and killed her mate and thought it'd be fun to torture the human. Her name means psycho cunt, though it was a toss up of that and fire crotch," Emmett let out a booming laugh at that. Good to know the big oaf hasn't changed. I internally rolled my eyes.

"Izzy, what about me? What's my nickname?" god, really? He really wants a degrading name? Eh, might as well tell him.

"Easy, you're CA," I replied waiting for the inevitable question.

"CA? What's that stand for?" ah, there it is.

"Con-artist, you want to know why?" he started nodding vigorously probably assuming it wouldn't be too bad.

"Because CA dear, I could deal with a best friend leaving, friends come and go. I could deal with Carlisle and Esme leaving, I already had my parents who loved me for me even if they weren't blood related. Rosalie always hated me and Jasper was never around so no problems there. I could even deal with the man I thought I loved leaving, he was only my first boyfriend I could've had tons more. You, however, were my brother in everyway but blood. You held the biggest piece of my heart. You conned your way into my very soul and than left without as much as a fuck you. Therefore CA was most fitting."

I almost lost my smile thinking about my once brother but no more tears would be shed for any of them, they were no longer my family. Sensing my discomfort Riley stepped next to me and grabbed my hand giving it a gentle squeeze to let me know he had my back. My smile returned.

"Hey, it's all good though. After all, what doesn't kill you makes you stronger," I said.

"And crazier," Riley mumbled with a smile. I glanced at him quickly and giggled.

"You know you love it Ri, don't lie. After all, you wouldn't have had so much fun and freedom if it weren't for me. Robin had wanted to keep you as her new play thing. Not everyone can handle playtime as well as me ya know. You would have eventually cracked." I used Robin not wanting to inform the vamps working for Dumbledore that I knew where Trixie was and Riley knew about our nicknames.

"Yea, no one can take it like you can champ," he replied with a proud yet mischievous smile. Yea, that definitely sounded perverted and Abby hissed a laugh. I smacked Riley's arm and rolled my eyes as Edward growled again.

"Well, it was nice conversing with you all but I do believe my class should be back in a few minutes and you all are going to be helping," I smirked thinking about my planned demonstrations. I shooed them off to find Potter so I could relax before the class came back.

I realized Rosalie never said anything to me after calling her BB and actually looked ashamed for her actions towards me all those years ago. Edward was constantly eyeing me and growling at Riley and Chan. Jasper was looking at me with guilt and pride, odd combo I know. Emmett looked utterly heart broken. Alice was what really got to me though, she looked pissed. Like ready to go Dracula and 'I vant to suck your blood' on me. Eh, o well, the class will be back soon and I get to show off Chan and have some fun with the vamps.
