Chapter 2

"Wow! Really? Nice to meet you! I'm Phineas," the redhead said enthusiastically. He held out his hand with which Calvin shook but something was off. Phineas noticed the other boy's smile and his general vibe sent chills down Phineas' spine. The once happy grin was replaced with a small frown, but noone noticed this except the Fireside girl. Once they retreated from their shake, Phineas turned to his step brother. "You never told me about your biological brother."

"I didn't know I had one," Ferb confessed. Phineas was usually the optimistic one but something about Calvin set off many red flags in his mind. He was growing suspicious but tried not to show it. He knew his friends would think he's crazy if he thought Calvin was off and his brother would definitely not forgive him. So he decided to play it normally, but he would be keeping an eye on him.

"Our biological mother divorced our father but the deal was while I took my mom, Ferb went with dad," Calvin explained. The others nodded in agreement. "Back when we were together though, we were inseparable as we built many things like toys and what not. On the way here, he told me that you guys do the same."

Phineas and Ferb smiled proudly at the thought.

"Hey, can I use your restroom?" Calvin asked.

"Sure, I'll show you the way," Phineas offered. He was thinking that he knew he was overreacting about Ferb's biological brother. It was absurd. He was getting used to the new kid even though he just met him. "Here we go it's right in he-" Phineas was cut off by an arm pinning him against the wall.

Calvin's arm.

"Calvin?! What are you doing?!" Phineas asked frantically.

"I saw you eyeing me. You think I'm suspicious looking and I don't like it. I will tell you one thing and one thing only… Ferb's my brother. You never belonged with him and I will do anything in my power until he forgets you." He roughly let go of Phineas and left to go back into the backyard. Phineas just stood there, shocked. After a few moments to gather himself, the young inventor headed back into the yard slowly. 'I won't let this guy take Ferb away from me' Phineas repeatedly thought.

"There you are Dinnerbell. We thought you got lost in your own house," Buford jokes. The redhead paid no attention to the comment and glared daggers into Calvin, who smiled sinisterly. No one noticed this though.

"Ferb, I know what we're going to do today," Phineas said with his catchphrase but his eyes never left the 'biological brother'. The whole team did notice this but shrugged it off as nothing. They all waited expectantly for Phineas to tell them what they were going to do and how but CCalvin was the first to speak. "Hey Phineas? Why don't I help you with the plans and building. It would be just like old times with me and Ferb."

"... Fine," Phineas muttered and motioned his head for Calvin to follow him. They both returned from the garage with a blueprint and a tool box. The gang looked at what they were doing and started building (the supplies were already called by Isabella). Throughout the session, everyone was having a good time.

Except Phineas.

He was constantly being sabotaged with his work by Calvin and everyone was getting frustrated with his 'mistakes'. Though they all thought the redhead was having an off day, he didn't sleep at all at night after all. At one point even Calvin was getting annoyed because his plan wasn't working, so he tried a different approach. As Phineas was getting some bolts from the tool box, Calvin snuck behind Phineas and SLAMMED the tool box lid on the inventor's exposed hands which he immediately cried out in pain. Everyone stopped what they were doing and hurriedly went to check Phineas, while Calvin tried to act innocent as possible but Phineas knew it was a lie.

"Phineas! What happened?" Isabella urgently asked as she helped open the tool box revealing Phineas' hands with a blood marked line across them. Everyone gasped at the injury and soon their expressions were mixed with confusion, worry, and… satisfaction.

Calvin was satisfied.

"Nothing," the redhead muttered as he clenched his fists until they turned white as he glared daggers to Calvin. Ferb noticed this and decided to investigate later.

"I see Phineas knows how to take his pains like a man!" Calvin declared happily as he patted the young inventor on his shoulder. Though his only response was a low growl, though so quiet no one heard this.

"Let's just get back to work," Phineas mumbled as he harshly retracted from Calvin's hand. Only then everyone noticed the change in their optimistic friend. Since Calvin arrived, Phineas had been more harsh, annoyed and has given an attitude they never experienced before. But what they noticed more is that only Phineas did this to Calvin.

It was sundown and they had already finished riding the ride. Everyone enjoyed themselves, especially Phineas as he got to relieve some stress since the arrival of Calvin. As no one noticed, like usual, the ride magically disappeared when a green beam hit it. Everyone bid their goodbyes and all went home, except for the three boys. They all entered the house and was greeted by Mr. and Mrs. Flynn-Fletcher.

"Hello boys. Just to let you know, Calvin, you're going to be sleeping in Phineas and Ferb's room in a sleeping bag. Now go wash your hands, it's time for dinner then bed time," Linda said. The boys nodded in response and did what they were told. As they had dinner, it was noisy. Calvin, Linda, and Lawrence talked to each other while Phineas and Ferb ate their food in silence. Ferb noticed this and tapped his step brother's shoulder. Once the redhead looked up, Ferb gave a look that said 'Are you okay?', and knowing what he wanted to say, Phineas answered his unasked question as he forced a smile. "Yeah, I'm good bro."

Ferb did not believe this though and decided to drop it until after dinner. As bedtime arrived, Calvin went to brush his teeth first while the other two put on their pajamas, that's when Ferb decided to make his move. "Are you okay?"

"Yeah I'm fine man!" Phineas lied as he scratched his ear. But his step brother noticed this and called it out.

"You're lying. You always scratch your ear when you're lying. And now I know that something is wrong because you never lie."

" Since when do you ever talk this much?"

"Since when I started worrying for my brother."

"It's nothing. You wouldn't believe me even if I told you," Phineas sighed.

"Phineas. You're my brother and don't ever think that I won't believe you, got it?" Ferb spoke seriously.

Phineas nodded.

"Now tell me what's wrong."

"Calvin was the one who slammed the lid of the tool box on my hands," Phineas told him as he held up his blood dried hands. Ferb was shocked, to say the least. If it was true, why would Calvin do that? "What?"

"He was the one that did this. He was the one that made me mess up earlier. He was the one-" Phineas cut himself off. He started biting his lip as he hesitated. He didn't know if he should tell Ferb about what Calvin said about him being taken away.

"'He was the one' what?" Ferb inisted.

"He was the one who pinned me against the wall," Phineas decided to say. It was technically the truth as it did happen, it just wasn't the whole truth. But he was startled when Ferb did something he didn't expect.

Ferb started laughing.

"What's so funny?" Phineas asked, annoyed that his brother wasn't taking the matter seriously. Once he calmed down, Ferb spoke.

"Well don't you think it's a little stretch that my biological brother is doing those things to you?"

"It's true! You said you'd believe me!"

"What I do believe is that you need a little sleep. Pulling that all nighter must have messed you up, but don't worry. If Calvin is a problem, I'll sort him out. Promise?" Ferb said as he held out his hand. Although he was a little upset Ferb didn't believe him, Phineas shook his hand.

"I'm holding you on that."

"You're holding on what?" Calvin came into the room. Phineas and Ferb exchanged glances but they just shook their heads as they didn't want to talk about it.

"Okay whatever. Let's head off to bed."
