After seeing the movie I just had to write this. I practically fell in love with 2nd dimension characters so…yeah. I don't own Phineas and Ferb. Enjoy!

…

2nd Dimension

''I think the Tri-State Area can finally be at peace now.'' Major Monogram said as the Firestorm Girls took Doofenshmirtz away. All the others had just come from the first dimension back to the second.

''Yes…I can't believe the battle is actually over.'' Candace said and then looked at her brothers who were still hugging their pet.

''Yeah now we can relax and enjoy summer.'' Phineas said happily and his brother nodded. All the others looked confused.

''What's summer?'' Buford asked first. Both Phineas and Ferb looked at each other and smiled.

''You'll see. It's an amazing thing.'' Phineas said. Isabella seemed little interested about this though she tried to hide it.

''Well show it then…Phineas was it?'' Isabella said though her tone was softer than she intended. Phineas stared at her for a while. With all the things that were going on he never quite got a good look of her. ''Whatcha staring at?'' Isabella said in her tough voice again. Phineas broke out his trance and then turned around.

''Oh sorry…Anyway let's go to our backyard.'' Phineas said excited. Others were still little confused, but followed him anyway. Some of the Firestorm Girls followed them, though most of them went to escort Heinz with Major Monogram.

1st Dimension

''That…was a weird dream.'' Isabella said to herself once she woke up. Like always she had dreamed about Phineas and her getting together, but something felt odd about this dream. It felt almost vivid. She thought about the dream again.

''So none of us will remember any of today?'' Isabella asked from a man in green suit. Isabella couldn't remember seeing him before.

''That's right.'' Man answered without hesitation.

''Good.'' And then she did something she never thought she would. She kissed Phineas.

She had woken up before she had seen Phineas's reaction. She knew it was just a dream, but it still felt vivid to her.

''Maybe it's just my imagination.'' Isabella said and then looked out from her window. She was little surprised when she didn't see anything in Phineas's and Ferb's backyard. ''They probably haven't started yet.'' Isabella said and then changed to her usual clothes. She was just about to go out, but her mother stopped her.

''Isa…did you take breakfast?'' Vivian asked. Isabella froze when she realized that she hadn't eaten breakfast. She sometimes skips breakfast to see Phineas and this was one of those times.

''No…''Isabella admitted and turned towards her mother. Vivian looked like she was about scold Isabella, but she was more worried than mad.

''Isa you have to eat breakfast. I understand that you want to see Phineas, but you have to keep care of your health too.'' Vivian reminded her. Isabella nodded and looked down for a while before looking back up.

''I know mom…I eat at Phineas's okay?'' Isabella said and before her mother could answer she had went out from the door. She quickly crossed the road and knocked on the door. Linda quickly came to open the door and smiled at the girl.

''Good morning Isabella.'' Linda greeted and let her in. Before Isabella could state her business Linda spoke up again. ''Phineas and Ferb are still in their room…which is little strange since they usually wake up early.'' Linda said, but thought nothing else about it. Isabella thanked her and went upstairs. She entered brothers' room without knocking.

''Whatcha do…wow!'' Isabella said once he entered the room. The room was a mess. There were papers scattered all around the room and some weird machines that Isabella didn't recognize. Phineas himself was sitting on some kind of chair wearing a weird-looking helmet. Ferb noticed her and waved at her. Isabella returned the gesture. ''So…what's going on?'' Isabella asked from Ferb even though she wasn't expecting an answer.

True enough Ferb just stopped the machine Phineas was installed in. Phineas instantly opened his eyes and saw Isabella. He smiled a little and stepped down from the chair.

''Hey Isabella…sorry about the mess, but for some reason neither me nor Ferb can remember what happened yesterday so we're trying to remember it…by the way do you remember what happened yesterday?'' Phineas asked hopefully, but to his dismay Isabella shook her head. ''Okay...have you seen anything weird?'' Phineas asked.

''Well no…I did have a strange dream though.'' Isabella said. Phineas became slightly interested at this.

''Oh…what was it about?'' Phineas asked curiously. Isabella blushed a little as she thought about the dream again.

''It's really nothing important!'' Isabella said almost too quickly. Phineas looked at her confused and a small silence followed. ''A-anyway…what's day's project?'' Isabella asked to break the silence. Phineas immediately smiled.

''I'm glad you asked. We're going to…hey where's Perry?'' Phineas asked when he noticed that the platypus was gone.

Perry quietly sneaked into the living room so no one would see him. He walked towards the lamp and jumped on top of it. He stomped his foot once and a tube came from the ceiling and sucked him to his lair. To his surprise Major Monogram was in his lair in person instead of being on the screen.

''Good morning Agent P…or should I say bad morning. I'm sure you remember yesterday's events.'' Monogram asked and Perry nodded as a response. ''We noticed that we forgot one crucial detail after we erased everyone's memories. The first Other-Dimension-inator still works and Doofenshmirtz is back in his apartment and knowing his curious nature, there's no doubt he'll open the portal to second dimension again. You have to stop him Agent P.'' Monogram said and Perry saluted and flew off with his jetpack.

2nd Dimension

''And stay there!'' Adyson yelled when Heinz was thrown to jail. He didn't seem to be too depressed about being in jail. The jail was located in O.W.A.A. headquarters. O.W.A.A. stands for Organization With an Awesome Acronym…though no one expect Monogram himself thought it was awesome.

''Adyson. Isabella gave order for all the Firestorm Girls to come to Flynn's and Fletcher's house.'' Katie said. Adyson looked at her friend shocked.

''But why? We can't leave Doofenshmirtz alone. He'll escape.'' Adyson said. Katie said nothing. Instead she pointed at the window on the door. Adyson looked through it to see Heinz cuddle up to his toy train. ''I see…did Isabella say anything else?'' Adyson asked.

''She said that if Doofenshmirtz escapes during this time…we can do whatever we like to Phineas Flynn.'' Katie said and smirked a little. Adyson smirked back.

''Understood.'' Adyson said and the two of them ran off, leaving Heinz completely alone.

''Choo-Choo…nothing matters as long as you're with me.'' Heinz said as he cuddled to the toy train. However his bliss with his toy train only lasted for an instant as someone entered the cell. Actually enter is a wrong word. This person teleported to his cell. The person had a dark cloak and hood on so no facial features could be seen.

''Heinz Doofenshmirtz I presume?'' Person asked. Heinz looked up to the stranger surprised.

''What? How did you get in here…and how do you know my name?'' Heinz asked confused as he clutched his toy train harder. Person sighed.

''How can't I know you? You were ruler just half an hour ago. Anyway I need your help…for evil.'' Person said and then extended his/her hand. To person's surprise Heinz just turned around.

''I'm not interested. I'm happy here with my Choo-Choo.'' Heinz said and once again cuddled up to the toy train. Person sighed again, but then smirked.

''You mean that toy train?'' Person asked and Heinz nodded proudly. Person smirked wider and took out a small green gun. Person fired it and the toy train disappeared in a flash. Heinz looked at the stranger in horror.

''What did you do?'' Heinz said absolutely horrified. Person smirked once again and then fired with the gun again and the toy train appeared on his/her hand. ''Choo-Choo!''

''Listen now. You will cooperate with me or you will never see your precious Choo-Choo again!'' Person yelled angrily. Heinz had to wonder why none of the guards were able to hear them talking, but he decided to focus to the stranger again.

''Fine I'll cooperate, but just who are you?'' Heinz asked. Person smiled and then removed the cloak and the hood. Underneath the person wore a pure black dress with white lines on it. She also had a scar, but her scar went all the way from the left side of her forehead to her chin.

''I'm Professor Poofenplotz…the future queen of Tri-State Area and this world.'' Poofenplotz said and then laughed manically. She stopped after a while when she noticed something weird. ''Wow…those guards must be deaf or something.'' Poofenplotz said and Heinz nodded.

''Yea…yes I think they are.'' Heinz said. Poofenplotz then took out a remote and once she pressed one button both of them teleported out.

…

That was the prologue. There are couple things I'd like to say now.

1: The couples will be PhineasxIsabella both the first and the second dimension, Ferb will be paired with either Vanessa or Gretchen depending how the readers want and I'll probably add GingerxBaljeet. I might add other couples later.

2: I will use the second dimension versions that didn't appear in the movie. So there will be Second Dimension Stacy, Irving and some others.

3: Future chapters will be longer. This was just shorter since it was a prologue.

4: There might be some original songs, if I can think of any. I actually already have one in mind.

Review if you liked, review if you didn't like…no flames though. Also anyone waiting for Love Sickness to be updated…I'll try to do that soon.
