Chapter 1:What? How are they here?

Carlisle POV

Me and Esme were in the Great Hall at Hogwarts Witch Craft and Wizardry. We sat beside the headmaster and one of my old friends Albus Dumbledoor. Suddenly two balls of white light burst through the door and to the ground.(A.N. This is apperation.) Out stepped mine and my wifes only children. Isabella and Nathan. They grew up so fast. Then again they were one when we last saw them. We left left them because Aro Voulturi was trying to kill Isabella and Nathan. They gave us the choice to A:Give them up or B:Have them killed. Being the parents we are we chose A and gave them up. Now 16 years later here they are. Though they look really different. Bella had bubblegum pink hair that looked kinda purple, then a whitish shirt with ruffles at the bottom, black jeans, then a long dark purple jacket. Nathan had bright blue hair, then looked pretty normal, had a dark blue jacket with a red vest and checkered shirt on under, and also some dark blue jeans on.(Pic's on my profile.)

They walked up the Albus and said together,"Hello Headmaster Dumbledoor."

He stood and said,"Tonks?Teddy? How are you? It's been a few months. All is well?"

Tonks and Teddy? I was very confused. Their names were Isabella and Nathan. I asked loud enough for them to hear,"Nathan? Bella? What are you doing here?"

Their heads snapped over. Bella walked over to the other side of Nathan and he held her into him both of them not looking at us anymore. Dumbledoor said,"Nymphodora? Ted? Why don't you two wait in my office. I will be up soon with your parents."

Bella's hair turned red and she said,"Don't call me Nymphadora."

Nathan said,"Calm down. Your hair's red. I don't have any water to put out the fire with."

She chuckled and said,"Fine Teddy. But please Proffesor Dumbledoor do not call me Nymphadora. I just like Tonks."

He said,"I am Sorry Tonks, but it is your adoptive name is it not."

I said,"Only because mother likes constellations. Teddy's just lucky Dad got to name him. I'm stuck with Nymphadora. He's stuck with Ted."

I was really sad when she mentioned that their parents like we weren't. I looked at Esme and she looked as if she could cry. I held her hand to calm her down. Dumbledoor said,"Go up to my office I'll meet you there." They disappeared in smoke and exited the same way they came in. Dumbledoor sat down and said,"I swear those two can't go one day without apparating somewhere."

I said,"Albus. Isabella and Nathan-"

He said,"I know. Why do you think I said I would bring their parents up. You two are coming with me."

Esme asked,"Can we go now. I haven't seen them in the longest time."

He said,"Of course." He leaned over and talked to Minerva about this. She nodded and we went upstairs to his office. We walked in and Nathan was throwing a peice of something towards Bella. She caught it easily in her mouth.

She said,"Told you."

He said,"You must have cheated Tonks."

She asked,"And how dear brother of mine might I do that."

He said,"Telekenisis or just plain magic."

She said,"I in no physical or mental state used magic or my powers in anyway to win the beat."

He said,"What. You know I can't follow when you use that voice and big words."

She said,"I said,'In no possible way did I use magic or my power dumbo."

He said,"Thank You. So proffesor. We should get to why we're here."

Albus said,"We should, but after your parents go. We all need to talk."

Bella got up and said,"I don't think there's anything to talk about here Proffesor. They hate us and that's that."

I got up and said,"Bella that is not true. In any way. We would never hate you. Either of you. It pained us to give you away."

She asked,"Then why did you?"

She turned and ran out the door Nathan hot on her trail. Dumbledoor said,"Why don't you go after them. They probably went to the astronomy tower or Gryffindor in their room."

I grabbed Esme and we ran out. Esme said,"Why don't I check Gryffindor and you can check the Astronomy tower." I nodded and ran up to the Astronomy tower. I looked around and didn't see them. I looked around again and ran down to Gryffindor.

When I got there Esme was sitting on the couch. I asked,"What's wrong."

She said dry sobbing,"I can't find them. I checked everyroom. No one even knew she was here. Apparently she doesn't go to this school any more. She did till she was 14 then her and Nathan left education. I should be able to find them. Their our babies and we can't find them."

I said,"It's gonna be alright. I'll ask around and see if anyone knows where they are. You just wait here and see if they come back." I got up gave her a quick kiss on the head and ran out. I asked some of the paintings and they didn't know.

I finally came across a painting and asked,"Have you seen Tonks and Teddy Or Isabella and Nathan." One man in the painting said,"Yes they went into the room of requirements about 20 minutes ago."

I said,"Thank You." I ran back to Esme and told her then we ran down to the room of Requirements. The door appeared and we walked in.

I saw Nathan and Bella laying down asleep. Teddy snored and Bella didn't make a sound. I picked up Bella lightly to make sure she didn't wake up. Esme put Nathan around her neck and Carried him back with me and Bella to their room. I laid Bella in the bed and put the blankets tightly around her. I said,"Night Bella. I love you." I kissed her head and did the same with Nathan. Esme and I walked downstairs and sat down and waited till Morning. Who we saw coming in at 6 A.M. shocked us. It was a werewolf. An acually one.

He said,"Sorry I'm just looking for someone." He ran up the stairs and I heard him go into Bella and Nathan's room.

I said,"He's going in Nathan and Bella's room." We got up and ran upstairs. I walked in and I was horrified...

Sorry about the cliffhanger but I will update as soon as I can. Happy Thanksgiving.
