Chapter 11:

Phineas woke up the next morning and looked at his clock to see it was 8:45 am.

"Crap I slept in," muttered Phineas as he got up and rushed downstairs. He quickly gulped down his cereal and rushed towards the backyard tree. Phineas was about to enter his lair but was stopped by Ferb.

"Hey Phineas, I see you slept in," said Ferb smiling.

"Oh yea I was really tired," said Phineas. He quickly glanced at his watch and noticed it was 8:55. Phineas turned his attention back to Ferb who had just finished saying something.

"Phineas what do you think?" asked Ferb.

"What did you say?" asked Phineas.

"I was just asking if you think we should build the world's largest hot air balloon," said Ferb.

"Oh I don't know," said Phineas as he glanced at his watch again. Ferb saw this time and grew suspicious.

"Phineas are you sure you're ok?" asked Ferb.

"Yeah I'm fine, everything's fine Ferb, why wouldn't it be?" said Phineas nervously.

"Ok then I'm going to go inside and the blueprints," said Ferb as he slowly walked inside.

"Yeah ok I will be right here perfectly fine," said Phineas smiling nervously. When he made sure Ferb couldn't see him he pressed a button on the tree and was raised into his lair by a small elevator. When he got inside he saw Monogram talking with Doofenshmirtz and Perry. When he was noticed they stopped talking and walked over to greet him.

"Ah good you're here Agent P," said the Major.

"Yes, yes I am, sorry I took so long but I was distracted," said Phineas.

"No need to apologize we saw the whole thing on the security camera," said Monogram.

"Oh ok," said Phineas. Perry looked at Monogram for a second and the Major gave him a quick nod.

"So am I supposed to train or something like that?" asked Phineas.

"Oh yes sorry I got distracted there for a moment," said the Major. Phineas nodded and looked at Perry who had come back with two wooden swords.

"Your first training exercise is hand close combat training, tomorrow we will practice the long range portion. Phineas nodded again listening intently.

"Ok then you will fight this robot who will be holding the other sword so, defend yourself," concluded the Major as he stepped back and turned the robot on. The robot immediately turned on and charged at Phineas. Phineas grabbed the sword Perry had given him and blocked the attack. He tried going for the stomach but was blocked and kicked back several feet. He was dazed and before he knew it the robot was standing over him with the wooden sword pointed at his neck. The Major pushed a red button and the robot immediately receded letting Phineas stand up.

"Agent P you would have been killed if that was Andrew," said Monogram.

"Yeah but that thing was tough what level of difficulty is that on?" said Phineas.

"Level one," said Monogram. Phineas face palmed himself before regaining his composure.

"Are you ready to begin again?" asked Monogram.

"I was born ready," said Phineas smiling. Perry chuckled before becoming serious again.

"Agent P's this is not a game and I can't believe I just said Agent P's," said the Major. The two agents became serious again and Monogram started up the robot.

"This is going to be a long day of training," thought Monogram as he rubbed his forehead.

Flynn Fletcher Backyard:

Ferb came back out to the backyard a few minutes and found it empty.

"Phineas?" called Ferb. Suddenly Isabella walked into the backyard with the fireside girls and Buford and Baljeet.

"Hey Phineas watcha doin?" asked Isabella. Once she said it she noticed he was missing.

"Hey Ferb where's Phineas?" asked Isabella.

"I don't know he was here just a minute ago," replied Ferb.

"I wonder where he went," said Baljeet.

"Well I guess we need to find something else to do today," said Buford.

"Lets look around the neighborhood and see if we can find him," said Isabella. Ferb nodded and walked off with everyone else.

"Do we have to look for him?" complained Buford. Ferb glared at him quickly which shut him up.

The New Agent P's lair:

Phineas was now up to level three in combat training but still had to make it to level ten to pass. He was determined to finish on a high note but the day was running out quickly.

"Ok very good Agent P you passed level three and made it to level four," said Monogram. Phineas wiped the sweat off his brow before turning to the Major.

"Thank you sir I couldn't have done any of this before today," said Phineas saluting to the Major.

"No I am sure you would have found it in you eventually," said Monogram. Phineas nodded back before turning back to his opponent.

"Ok begin," said The Major. The new robot was easy for Phineas and he had it destroyed in under a minute.

"Um sir, are these robots getting easier?" asked Phineas grinning.

"No they are supposed to get harder but you have obviously made great progress within a few hours," said Monogram.

"Ok so what now?" asked Phineas.

"I think we finish off today with the level ten robot," said Monogram as he rubbed his chin.

"Yes sir!" said Phineas as he prepared for the final fight. Monogram nodded and pressed a button revealing a giant robot.

"And begin!" shouted Monogram.

Phineas nodded and carefully watched as the robot approached him with the wooden sword. Phineas drew his own sword and got into a battle stance. The robot swung straight at him as if to cut him in two but Phineas dodged it by rolling over to the left. He then proceeded to stab the robot in the side to weaken it. The robot saw this coming and quickly reacted by swinging his sword to the left and blocking it. The robot then tried to grab Phineas to throw him against the ground but Phineas cut off the robots hand and kicked it in the chest which sent the robot staggering back a bit which gave Phineas the time to get up and charge at the weakened robot. The robot saw this coming though and got out of the way just as Phineas tried to cut him in half. The robot hit Phineas in the chest sending him to the ground. The robot was about to step on Phineas' face but Phineas saw this coming and rolled out from under it. He jumped up and before the robot could react cut its head off.

"Very impressive," said Monogram as he patted Phineas on the back.

"Thank you sir," said Phineas.

"Ok it looks like you have mastered close combat and are ready for long range combat which we will do tomorrow," replied the Major.

"Yes sir," said Phineas saluting.

"Ok before you leave I want to replace the watch you have with this one we give to all our agents, it will tell you when to meet me here and it can also be used to contact me, but don't call between 3:30 and 4:00 because that's when I take a shower," said the Major.

"Ok," said Phineas standing up to leave.

"And Phineas you can't tell or let anyone find out you are a secret agent otherwise we would have to relocate you to a new place with a new family," finished Monogram. Phineas nodded and saluted one more time before leaving his base. When he got to the backyard he left the tree elevator and walked towards the garage. A few minutes later he heard voices and walked towards the backyard again wondering what was going on.

"I wonder where Phineas is," said Isabella.

"I don't know we looked everywhere," said Baljeet.

"Maybe Phineas ran away," said Buford.

"No he didn't," said Ferb sternly.

"Yea Phineas couldn't he wouldn't," said Isabella.

"Hey guys," said Phineas walking into the backyard. Everyone was silent for a second before they started shouting out questions.

"Phineas where have you been?" asked Isabella as she ran over to him.

"Hey Izzy I was just walking around town," said Phineas.

"Oh we looked everywhere for you," said Isabella.

"I'm sorry Izzy I didn't mean to worry you I just needed a day to do some personal thinks," said Phineas as he scratched the back of his ear. Isabella and Ferb immediately saw this but said nothing.

"Ok well I am really tired so I think I am going to go to bed early," said Phineas as he walked inside.

"Did anyone else but me notice Phineas was lying?" asked Ferb.

"Yes I think we all did," said Isabella.

"Why would Phineas lie to me?" asked Isabella on the verge of tears.

"Hey it's probably nothing," said Ferb as he hugged Isabella.

"Yeah I guess I shouldn't be overreacting just yet," said Isabella smiling.

"No, no you shouldn't," said Ferb.

"But just in case we should watch him closely to see why he lied," said Ferb. The others agreed and walked off to their separate homes. Phineas saw the whole thing and knew they were talking about him. He hated lying to everyone but he needed to in order to stay in Danville. Ferb walked up to his room and before he got their decided to check in on Phineas.

"Hey Phineas how are you doing?" asked Ferb.

"Oh I was just getting ready for bed," replied Phineas as he patted Perry on the back.

"Ok well I just wanted to say goodnight," said Ferb closing the door still wondering why Phineas lied.

Once Ferb left Perry stood up with his fedora on and sat down next to Phineas.

"Man Perry that was a close one," said Phineas. Perry nodded and returned to his original platypus form.

Phineas put his head on his pillow and fell asleep with Perry in his arms. But before he did he thought about how he was going to keep this huge secret from his friends.

Ok everyone that concludes chapter 11. Next chapter the rest of Phineas' friends could find out the truth behind Phineas' whereabouts. Also I hope you all enjoyed this chapter as much as I did.
