So here it is, chapter 4. Sorry, I hadn't posted in a while because of school, Writer's block and Tetris...

Ya, I got a little addicted at the game and had competitions with my-. You know what, I've kept you waiting for too long, no more ranting about random stuff... You may start reading...

Present

"So, see anything you like?" Phineas asked

"Daddy, I told you already. That orange one in the other store is perfect." Marie replied

"Why didn't you just say so?" he asked

"I did," Marie replied

"Oh…" Phineas replied

"Try listening to her sometimes, Phineas. You might like it." Candace said as she walked in holding a shopping bag.

"Is that it Aunt Candace?" Marie asked while running to Candace

"Yeah, mind trying it?" Candace asked

"Ok," Marie replied as she ran to the dressing room.

"She's a cute creation, little bro. Take care of her." Candace said

"Ok, I will." Phineas replied.

Meanwhile, with Ferb…

"So dad, um… you like mom very much, don't you?" Thomas asked

"Yeah," Ferb replied

"Well… while I'm here… with you… the young you… in love… um… how could you impress a girl?" Thomas asked

"That depends, what's she like?" Ferb asked

"Um, she's cute, kind, beautiful and uh, kind of… annoying." Thomas replied

"Maybe, give her a flower or something." Ferb replied

"Yeah... she's oblivious." Thomas replied

"Hmm… kinda interesting, who's the girl?" Ferb asked

"Marie," Tom replied

"Wait, isn't she your cousin?" Ferb asked

"Yeah, but Marie and I are not blood-related, so we can still be together." Tom replied

"Yeah, I know that, but doesn't it feel kinda… awkward, for Phineas and I?" Ferb asked

"You know Phineas and I are step-brothers and we'll have kids, and that's you two, and those kids will date… um… well…" he added

"I know dad," Tom interrupted, "I know."

Future

"Phineas, please sweetie, take a rest." Isabella insisted

"No," Phineas replied

"Sweetie, they'll be fine." Isabella said

"Honey, you're not sure about that. Everything they build, or probably touch, blows up." Phineas replied

"We just need to trust them." Isabella said

"Trust them? I've trusted them before, but everything goes wrong! How can I trust them now?" Phineas snapped

"Ugh! You're so stubborn! Why don't you just rely on me this time?" Isabella asked as she stormed out of the room.

Present

"You done yet?" Phineas asked as he knocked on the door

"Just a minute," Marie replied.

After a few minutes, the door opened

"Here comes the princess!" Phineas announced which made Marie giggle

"Am I really that much to you daddy?" Marie asked

"Of course Marie. Now, ready to meet mommy?" Phineas asked

"Yay!" Marie squealed.

Just as they were about to go to meet Isabella, they saw Ferb and Thomas.

"Hey Marie," Tom greeted

"Tommy!" Marie squealed

"Marie, don't shout." Phineas warned which made Marie close the imaginary zipper of her lips and smile.

"So, what are you doing here? I thought you were with Vanessa." Phineas said

"Yeah, we were. But Tom wanted to do something today. Tom, would you do it?" Ferb asked.

Thomas walked near Marie, took a deep breath, looked back to his dad, probably because of hesitation, then revealed a single red rose. Marie then gave Thomas a curious look.

"Um…" was all she could say then accepted the red rose.

"A single rose, because you are the only girl for me." Thomas said

"Um… thanks." Marie replied

"Uh… she doesn't know that Tom likes her, right?" Candace whispered

"Yes, yes she doesn't. Much like her father." Ferb replied which made Phineas look at them curiously.

"Seriously, you can't really forget that?" Phineas asked which made the two laugh uncontrollably.

"Yeah Phineas, she's really your child." Candace said which made Ferb laugh even harder.

"Come on Marie; show him what you feel about him already." Phineas whispered

"What's that, daddy?" Marie asked

"Nothing," Phineas replied quickly which made Ferb and Candace laugh their heads off.

"Knock it off!" Phineas snapped

"Oh, and one more thing, Marie do you easily get mad?" Candace asked while taming her laugh.

"Yeah," Marie replied

"How 'bout, crack?" she added

"Well, sometimes." Marie replied which made Candace and Ferb choke on a laugh.

"Oh man, when I'm 34, bring Marie to my place everyday." Candace said through laughs.

"Ugh," Phineas started, "How do you know that I crack? I do not crack! Where in the world did you get that?" Phineas cracked.

They all just stared at Phineas for a minute or two before Marie talked again

"Mom said that I got it from daddy." She said which made Candace and Ferb laugh again

"She also said that she knew that daddy crack when they were at that deserted island in Paris, France. She also said that you and uncle Ferb were with them." She added

"Oh, I remember, the summer solstice." Candace said.

Phineas then walked to where they will go while the others followed him while laughing.

Future

Meanwhile, Phineas thought what he just said to Isabella and made himself feel guilty about it.

"Isabella," he said

"Are you in here?" he added as he stuck his head in their bedroom.

"Yeah," Isabella replied while looking up from her book.

"Sorry Izzie, I, I was just…" he said

"No need to apologize, sweetie." Isabella interrupted

"Oh Izzie. I just don't know what to do, it's my fault that the kids are stranded in the past." Phineas said as he sat on the bed next to Isabella.

"It's ok, you don't have to blame yourself." Isabella said as she hugged Phineas, "It's ok,"

Present

"Hi Isabella," Phineas greeted through the phone

"Hi Phineas," she greeted back

"So, are you there yet?" he asked

"Yeah, where are you?" she asked

"I'm near. Oh look! I can see you." Phineas replied then hung his phone up.

Isabella then looked everywhere but couldn't find him anywhere. Phineas surprised Isabella by a hug from the back.

"Here I am!" he said

"Hi," Isabella replied as Phineas let her go.

"So, um… who's the person you want to introduce?" Isabella asked

"Oh right! Don't get mad, don't freak out ok?" Phineas asked

"Ok," Isabella replied

"Um, Marie, could you go over here?" Phineas asked then came out Marie.

"Mom!" Marie squealed as she ran to Isabella then hugged her.

Isabella then gave a confused and startled look at Phineas.

"Um… Phineas," she started

"Yes?" Phineas replied

"Mind telling me why there's a nine year old girl hugging me and calling me mom?" she asked then Marie let her go

"Well you see, I-." he was cut off by Isabella raising her hand

"Don't tell me that this is your child and you got me as a girlfriend to be her mommy," she said

"Well, sorta I-." he was again cut off by Isabella.

"Phineas Flynn, you are such a user!" she snapped then walked away.

"Isabella, wait let me explain." He said as he covered Isabella's way.

"Go ahead," Isabella said while gesturing her hand.

"You see, she's my daughter, yes, but from the future. She's your daughter too Izzie. She's our daughter." Phineas said which made Isabella silent for a minute then jump up and down and hugged Phineas, and without realizing, kissing him.

"Oh sorry," she said after she pulled away

"No, it's ok," he replied, "I liked it by the way." He added which made Isabella giggle.

"Oh, I almost forgot. She's oblivious, just like her daddy." Phineas said proudly

"Hmm… That's not worth being proud of Phineas, well; at least she got it from you." Isabella replied.

There you go, chapter 4... Hope you like it, and for people who did, glad you liked it...

hotshot: There ya go. I added a little Thomarie, it made it a little more hard. I had to survey people if I'll make it romance or humor, turns out, people love humor more than romance. It's worth the time and hard work, at least I got it finished... :) Thanks for the idea, though.

WordNerb93 : Maybe soon, things will go bad. Especially now that Phineas from the future had stopped working on the time machine...

Oh, the reason why Phineas is building the time machine for a long time is because he's the one who always plan but only gets to work a little, but it Ferb will be the one to build, it'll only take, mmm... I don't now, 1 and a half hour...
