A/N: Stinkfly3 here. The beach scene was also Myron Greenleaf's idea.
Phineas and Ferb invited their respective girlfriends on a double date at the beach. Phineas was wearing dark red swimtrunks, Ferb was wearing green swimtrunks, Isabella was wearing a black bikini, and Vanessa was wearing a pink one-piece.
"Oh Phineas," Vanessa said. "This is the most romantic thing you ever did. Is there anything else that can make this day even more outstanding?"
"Sure thing," Phineas said. Then Ferb took out his guitar and played a somewhat familiar melody as Phineas began to sing.
Hey there Vanessa,
What's it like in your perspective?
I'm a clueless lovesick guy
But girl tonight you look so pretty
Yes you do
Danville can't shine as bright as you
I'm sure it's true
Hey there Vanessa,
Don't you worry about the darkness
I'm right there if you get worried
Give this song another listen
Close your eyes
Listen to my voice it's my disguise
I'm by your side
Oh it's what you do to me,
Oh it's what you do to me,
Oh it's what you do to me,
Oh it's what you do to me,
What you do to me
Hey there Vanessa,
I know times are getting hard
But just believe me girl,
Someday I'll pay the bills with love and heart
We'll have it good,
We'll have the life we knew we would
My word is good
Hey there Vanessa,
I've got so much left to say,
If every simple song I sang to you
Would take your breath away
I'd sing it all,
Even more in love with me you'd fall
We'd have it all
Oh it's what you do to me,
Oh it's what you do to me,
Oh it's what you do to me,
Oh it's what you do to me
A thousand years seems pretty long,
But we've got time to plan it out
I'd wait with you if I had no other way,
Our friends would not make fun of us
Since we'll just laugh along because we know
That none of them have felt this way,
Vanessa I can promise you
That by the time we get through
The world will never ever be the same
And you're the cause
Hey there Vanessa,
You be good and don't you worry
Two more years and we'll be done with work
And I'll be making history like I do
You know it's all because of you
We can do whatever we want to
Hey there Vanessa here's to you
This one's for you
Oh it's what you do to me!
Oh it's what you do to me!
Oh it's what you do to me!
Oh it's what you do to me!
Oh it's what you do to me!
What you do to me.
When the song was finished, Vanessa hugged Phineas and he hugged back.
Phineas...
The 11-year-old boy flinched. He could have sworn he heard his mom say his name.
Phineas...
That was his dad. "What's going on?" Phineas thought. "I thought my parents are-"
Phineas woke up in a cold sweat. His was in his own bed in his own room. The beach scene with Ferb, Isabella, and Vanessa was only a dream. Just a really good dream.
We're sorry to wake you up so early.
Phineas looked around. He just heard his mom talk to him...but she was nowhere to be seen. "Mom?" he asked out loud, his voice cracking with sadness.
We're outside.
Phineas checked the clock on his nightstand, which read 12:01. He got out of bed, put on his black overcoat (since he was sleeping in a large white t-shirt and dark grey boxers) and red and blue striped converse sneakers, and went outside.
Phineas walked over to the backyard, where he heard the voices coming from. It was a very windy night, but all he heard was the voices of his dead parents.
My, look how much you've grown these past few months, Lawrence said. It seems like it was only yesterday you and Ferb were playing Doofopoly in the living room. Now look at you. You're a hero throughout all of Danville.
"How did you know about that?" Phineas asked. "You and mom died before the second Normbot stronghold was destroyed."
We saw the whole thing from above, Linda explained. You single-handedly destroyed the remaining six strongholds.
"But I disobeyed you," Phineas sadly said. "If I stayed inside like you told me, none of this would be happening. You would both be...alive..."
But you wouldn't have met Vanessa, Linda pointed out.
Your mother is right, Lawrence said. We saw how much you cared about her.
Phineas let out a sad sigh, knowing his parents probably knew about her heading back to Colorado. "I just want to be with her all the time," he said. "I want to hear about her day, and tell her about mine. I want to...hold her hand, and...smell her luscious coconut-scented hair..."
At that point, Phineas' mind was in a Vanessa-centered fantasyland. That always happened to him when he thought about his love.
Then why did you let her go? Lawrence asked, snapping Phineas out of his thoughts.
"Sh-She didn't want to deal with a...long-distance relationship," Phineas answered. "I begged her not to go, but she left anyway." He sighed miserably. "I would do anything to get her back."
It's okay, Phineas, Linda said. You just have to move on.
That was it for Phineas. The 11-year-old boy collapsed onto the ground, quietly crying as he closed his eyes. The earliest memories of his life were during the beginning of the Doof era, where he was always safe and protected with his family. He remembered the night Perry disappeared when he was only two years old. Linda held him in her arms that night, stroking his hair and singing him lullabies until he fell asleep.
Since then, Phineas developed a strong need for being with his family, and it became stronger as the years went by. He stayed inside during those years, never seeing anyone else beside his parents and siblings. But as he got older, he felt comfort, and that comfort was all he needed to survive.
But that changed on August 5th. A few days after Doofenshmirtz was arrested, Phineas witnessed his parents die right before his eyes. He eventually moved on when he fell in love with Vanessa. And with Candace spending her free time with the Johnsons and Ferb socializing with the Garcia-Shapiros, Phineas thought Vanessa would introduce him to her family as well.
But with her gone, what was left for Phineas? His family was abandoning him and he had nowhere else to go. All of his other friends were also moving on. Dr. Baljeet gained an interest towards weapons designer Wendy Stinglehopper during the team's Halloween party, while Buford has shared a bowl of nachos with Firestorm Girl Adyson Sweetwater several times during lunch breaks nowadays.
But Phineas was all alone. And as he laid on the ground in the cold weather, he started to question his own existence. He wondered if anyone else would even notice if he vanished one day and never came back. He could take out his knife, aim it at himself, and see his parents once more.
"C-C-C-Can I come live with you?" Phineas asked. "No one would even know I'm gone."
Phineas Vincent Flynn, don't you dare kill yourself, Linda said. I don't want you to give up on life.
"But there's nothing left for me," Phineas explained. "Why should I stay in a world where no one is there for me?"
But there was no reply.
"Mom?" Phineas asked frantically. "Dad? Are you still there?"
No reply again.
Phineas got back on his feet and looked at the dark purple sky. "MOM! DAD!" he hollered. Then he ran out of the backyard and into the street, still calling for his parents.
After what felt like hours of searching, Phineas collapsed onto the middle of the road, exhausted and depressed from his search. The last thing he remembered was feeling tears come from his eyes as he drifted off to sleep.
