Sisterly Love

Chapter Two

Just as Isabella was about to speak, the doorbell rang.

"I got it mom!" I yelled almost at the top of my lungs to her, even though she was just in the room across the hall.

"Ok sweetie!" she yelled back in the same pitch.

I opened the door to find two boys about our age. One was wearing a black shirt with a skull on the front, set up in a "Punisher" style. He wore large, red hiking boots, with green khaki shorts. His hair was brown and cut in a buzzcut style. He had deep blue eyes, and also appears to be somewhat overweight, although he didn't seem to mind. He was holding another, smaller, kid under one arm and a platypus under another. He was wearing a white T-shirt with blue overalls on top. He had blue sneakers. His hair was short and black. He also looked Indian.

"Um…Can I help you?" I asked putting on my shy act again.

"Hey Isabella. Have you seen Phineas and Ferb? We found their pet platypus outside their door and we found out that they weren't home." The bigger kid said.

"An why are you wearing blue instead of pink?" the smaller kid looked up at me when he said this.

"Just one moment please." I whispered. I offered them inside and they stepped in, the smaller kid carried. "May I take him?"

"Uh, yeah. Sure." The bigger kid said looking confused.

"Thank you. Please wait here." I said as I bowed and walked off to the kitchen with the platypus. I then whispered to the platypus. "I know your secret. But don't worry. I won't tell. You can count on that."

He only responded with his 'Grrgrgr' noise.

I walked into this kitchen, still acting shy, and I said "Phineas. Ferb. Some friends are here. They claimed to have found your pet here." I started to pet him and he started to make noise. I smiled.

"Friends? Does she mean Buford and Baljeet? What do they want?" Phineas asked.

I shrugged. "They just told me to get you over there. Please follow me." I turned around and started to walk. They followed behind me.

"Here you go. Are these the one's you were looking for?" I asked, still not making eye contact while petting the platypus.

"Yeah. Thanks. By the way, why are you acting weird Isabella?" the big one asked.

"I'll be in my room if anyone needs me. Please don't come in, but you can knock on the door lightly to get my attention." After that I just turned and walked away with the platypus still making noise.

I gave the platypus to Isabella and walked to my room to meditate.

With Phineas, Ferb, and the others….

"Man. What is UP with that girl? She's acting so wimpy." Buford said letting go of Baljeet who plopped on the floor.

"That wasn't Isabella you know. That was her twin." Phineas said shrugging. "Anyways. Why did you want to see us?"

"So…since when did she have a twin?" Buford asked.

"Well, since you can only have a twin if you were born together, I'd say her whole life." Baljeet said and he got up and dusted himself off only to be knocked down again by Buford.

"What's taking so long? I'm all alone in that room with Perry. Oh. Hi Buford. Hi Baljeet." Isabella said walking in holding Perry in her arms. "What's up?"

"Well we DID just find out that you had a twin we never knew about." Baljeet said.

"Well I never knew about her until two days ago and I haven't seen you since so, yeah." Isabella said shrugging. "I'm bored. I'm gonna go eat more cake."

"Cake? You have cake? I want some!" Buford smiled and raised his hand up "Lead the way!"

"We have to get Annarenee`'s permission first. C'mon. Her room is this way." Isabella said while walking to my room. She knocked lightly and the door opened a bit on its own. She peeped in and gasped at what she saw.

Back with me….

I had put on a dark blue robe with a hood, the hood was over my head, and was chanting an incantation that focused my mind so I could levitate off the floor about 2 feet. It had a side effect of things fly across the room.

Good thing these walls and door are soundproof. I thought as a book flew off the shelf onto the floor.

"Azarath Metrion Zinthos…Azarath Metrion Zinthos… Azarath Metrion Zinthos… Hiya!" I yelled taking control of a book and flinging it at the wall, leaving a huge indention in it. "Dang it. Now I have to fix that too."

As I spoke I felt myself falling because of loss of concentration. "Waahhhh!- oof. Owie. That hurt. Alright. I'm done with that one." I started to pout while the 'Book of Azarath' flew over and I used magic to flip the pages. "How about the pass through walls…nah…ooo. Take control of an animate object. Sweet! I'll try that later."

"Annarenee`?"

I turned at the sound of a voice and I saw Isabella peeping in the door. I quickly grabbed the book and hid it behind me. "Hey Isabella. What's up? I thought I said don't come into my room."

She walked in. "I know. But Buford wanted some cake so I thought we should ask you. You know. Because you made it." She said coming in but leaving the door open so I can see the others.

I mentally slapped myself for not putting a lock on the door but I put on a sweet smile. "Sure. Just don't have them eat too much. Wouldn't want them to get a stomach ate or maybe something worse."

A few moments passed. "You saw didn't you?" I said dropping the act of fake glee.

Isabella nodded. "Did they?" She slowly shook her head no. "Ok. Good. I will explain later ok?" she nodded again.

"C'mon. Let's go do something and get out of this place. I'm bored." I exclaimed taking off the robe and throwing it on my bed before plopping down on it.

"Ok…well what do you want to do? It's about 11:00 right now." Phineas asked while staring at the clock on the wall.

"How about making the world's biggest ball of cheese?" I suggested. Everyone stared at me. So I shrugged and looked away as I spoke. "What? I like cheese."

"Well ok then. Let's go make us a ball of cheese!" Phineas yelled while everyone else yelled and ran out. Phineas came back about 2 seconds later. "Are you coming?"

"Well I was about to get up, so yeah. By the way. Why did you come back so fast?" I got up and walked over to him, intimidating him so he was nervous again.

"Oh. Well. I, uh, I wanted to make sure all my friends come and have fun." Phineas said averting eye contact while rubbing his arm. "Hehehe…" He put on a hopeful smile.

"Sure, I'll take it. For now." I said as I slyly smirked at him. "You're kinda funny. That's good. Cute and funny are a good mix." I said as I walked to the doorway. "Close the door all the way on your way out. And don't touch anything." I exited to the kitchen.

With Phineas…..

Did she just call me cute? Wait, why do I care?

I was walking to the front door pondering about it when someone tapped my shoulder. I turned and I saw Ferb.

"Oh. Hi Ferb. Do you need anything?" I asked facing him. He only pointed and I looked.

I saw that he was pointing to everyone by the front door waiting, Annarenee' holding Perry. I suddenly remembered what we were doing. "Ferb, I know what we're doing today!" I said as I ran out the door, everyone else.

With Annarenee'…..

Right when we got to Phineas and Ferb's backyard they had started the project. I had stayed behind by the gate and whispered to the platypus. "If you have something you need to do, make a noise, wait two seconds, and make the noise again."

He did just that. "Grrgrgr…Grrgrgr."

"Ok. Here you go. Make a noise if you need me to cover for you." I whispered while putting him down. "If not then you can just walk off."

He turned to look at me and nuzzled his face into my leg before scurrying off. I stood there smiling to myself, head slightly down, hands clasped together in front of me, and my foot make shapes in the grass. I could feel a pair of eyes looking at me so I looked up. It was Phineas. As soon as I looked up he turned his head back to his work on his desk again.

Well that was odd. Wonder what's up with him.

As I walked up to him he got a nervous look in his eyes. "Um, hey Phineas?" I asked to get his attention once I was in front of his desk.

"Yeah?" He refused to look up.

I folded my hands and rested my head on them, propped up with my elbows on the desk. "Were you staring at me over there?" I asked.

"Uh, no. I wasn't" he rubbed the back of his neck.

He's lying to me. He's bad at that.

"I can tell your lying to me. Please don't lie to me. I hate liars." I said averting my eyes to the side to look at how well the project is being built.

"I'm not lying." He said, still refusing to look up.

"*sigh* Ok then. Whatever you say." I got up and walked away pretending to be upset.

"…wait. Annarenee'." He ran up to me.

My plan is going perfectly.

"Hmm?" I asked, holding my arms, my head turned to the side.

"Please don't be mad. I…I was staring at you- But not for the reasons you might think!" he said the last part fast, waving his hands at me.

"What was the reason?" I asked as I looked at him, careful to show hurt and distrust in my eyes.

"Because you…uh…weren't helping and I thought…you might want to?" Phineas said.

"Oh. Well why didn't you just tell me in the first place?" I asked putting my hands on my hips, bending low, and walking around him, eyeballing him.

He gulped. "I, uh, thought you might laugh at me." He said looking down.

I couldn't help but giggle at him. "Why would I laugh at that? See what I mean? You're a funny kid. That's why I like you and your friends. C'mon. Let's go make a big ball of cheese." I said while grabbing his hand and running over to the others.
